I have two menu buttons in separate fragments as shown in the codes below. Strangely, when I press the button ("Home") in the first fragment (and of course, the button in the second fragment), it fires the onOptionsItemSelected in the 2nd fragment.
If I have onOptionsItemsSelected in both fragments, the one in the first fragment is fired for the buttons in both fragments, and the menu id appears as 1 for both buttons.
What can I do to make different buttons do different things? (by firing different events or by generating different menu id's.)
public static class MenuFragment extends SherlockFragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
menu.add("Home").setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);
}
}
/**
* Second fragment with a menu.
*/
public static class Menu2Fragment extends SherlockFragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
menu.add("Filter").setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) // This gets fired when Menu 1 is selected
{
int id = item.getItemId();
Toast.makeText(getActivity(), "Option " + id+ " selected", Toast.LENGTH_SHORT).show();

so I have an app with three different buttons(parent buttons) on pressing any of them, the custom alert dialog with 9 different buttons is displayed but the functions of these 9 buttons within the alert dialog are different depending on which of the three parent buttons called it. On pressing any of the 9 buttons, I want the app to perform a particular function and then close the alertdialog. Now the problem is that I can easily call the alert dialog by calling the method showcustomdialog(); that I created but I can't dismiss it using alertdialog.dismiss(); inside the OnClickListener of the parent button since the method has a void result type. I've tried using if-else statements but it doesn't work. How can I achieve what is required?
The method:
private void showCustomDialog() {
ViewGroup viewGroup = findViewById(android.R.id.content);
View dialogView = LayoutInflater.from(this).inflate(R.layout.dialog_main2, viewGroup, false);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(dialogView);
final AlertDialog alertDialog = builder.create();
alertDialog.show();
}
I am calling the meathod and using it as follows:
parentbutton1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
showCustomDialog();
alertbutton1.getId();
alertbutton1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
textView1.setText("500");
function();
//I want to dismiss the alertdialog here.
}
});
alertbutton2.getId();
alertbutton2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
textView1.setText("1000");
function();
//I want to dismiss the alertdialog here.
}
});
and so on.
I figured out a solution for you using AlertDialog.
parentbutton1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
createDialog();
}
});
Then the method MUST be a private or public AlertDialog:
private AlertDialog createDialog() {
LayoutInflater inflater = (getActivity()).getLayoutInflater(); // for fragment or getLayoutInflater(); for activity
View v = inflater.inflate(R.layout.dialog_add_new_list, null);
Button okButton = v.findViewById(R.id.confirm_button);
Button cancelButton = v.findViewById(R.id.cancel_button);
final AlertDialog dialog = new AlertDialog.Builder(getActivity()) // for fragment or AlertDialog.Builder ( this ) for activity
.setView(v)
.show();
okButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
}
});
cancelButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View p1) {
dialog.dismiss();
}
});
return dialog;
}
P.S. Replace the ids I used to create this sample with yours.
I am having a problem in Android Studio. I have got two different buttons and a textView. The effect that I want is as follows:
CASE 1: When bt1 is clicked, "A" is displayed in textView. When the bt2 is clicked, "G" is added in textView so the textView displays "AG".
CASE 2: When bt1 is clicked, "A" is displayed in textView. When bt1 is clicked again, it disappears and the textView is empty.
CASE 3: When CASE 1 is done, as bt1 is clicked, "A" is removed so that textView displays"G".
Your help in altering my code is much appreciated. Thanks in advance!!
Main Activity code:
public class keyboard extends AppCompatActivity {
Button btn1,btn2,btn3;
TextView text;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_keyboard);
text=(TextView)findViewById(R.id.txt);
btn1=(Button)findViewById(R.id.bt1);
btn2=(Button)findViewById(R.id.bt2);
btn1.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v){
text.setText("A");
text.setVisibility(text.getVisibility() == View.VISIBLE ? View.GONE : View.VISIBLE);
}
});
btn2.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v){
text.setText(text.getText() + "G");
text.setVisibility(text.getVisibility() == View.VISIBLE ? View.GONE : View.VISIBLE);
}
});}}
Here you go..
public class Keyboard extends AppCompatActivity {
Button btn1, btn2;
TextView text;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_keyboard);
text = findViewById(R.id.txt);
btn1 = findViewById(R.id.bt1);
btn2 = findViewById(R.id.bt2);
btn1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
text.setVisibility(View.VISIBLE);
if (text.getText().equals("A")) {
text.setText("");
text.setVisibility(View.GONE);
} else if (text.getText().equals("AG")) {
text.setText("G");
} else {
text.setText("A");
}
}
});
btn2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
text.setText(String.format("%sG", text.getText()));
}
});
}
}
been alright so far. I try to use docs or find my issues.
However my mainActivity has 4 buttons. These buttons depending on which view is clicked passes the R.id.button. I pass this value into an intent which Activity2 uses bundle to get id integer. I then setContentView using this.
However im having issues getting correct view to inflate now, it seems like its loading an old layout. My aim is to inflate 3 separate layout on Activity2 depending which button was clicked.
I know my other other button does inflate another activity and get proper xml layout.
Why are my other 3 buttons not inflating on Activity2 properly?
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
Button pizza;
Button hamburger;
Button icecream;
Button history;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pizza = findViewById(R.id.buttonPizza);
hamburger = findViewById(R.id.buttonBurger);
icecream = findViewById(R.id.buttonIceCream);
history = findViewById(R.id.buttonHistroy);
pizza.setOnClickListener(this);
hamburger.setOnClickListener(this);
icecream.setOnClickListener(this);
history.setOnClickListener(this);
}
#Override
public void onClick(View v){
int idView = v.getId();
switch(v.getId()) {
case R.id.buttonBurger : startOrderActivity(R.layout.burger_layout);
makeToast(idView);
break;
case R.id.buttonPizza : startOrderActivity(R.layout.pizza_layout);
makeToast(idView);
break;
case R.id.buttonIceCream : startOrderActivity(R.layout.icecream_layout);
makeToast(idView);
break;
case R.id.buttonHistroy : startOrderActivity(R.layout.history_layout);
makeToast(idView);
break;
}
}
private void startOrderActivity(int id){
if(id != R.layout.history_layout) {
Intent intentOrder = new Intent(this, MakeOrderActivity.class);
intentOrder.putExtra("layout", id);
startActivity(intentOrder);
}
else {
Intent intentOrder = new Intent(this, OrderHistoryActivity.class);
intentOrder.putExtra("layout", id);
startActivity(intentOrder);
}
}
public void makeToast(int id){
String txt = String.valueOf(id);
Toast newToast = Toast.makeText(getApplicationContext(),txt,Toast.LENGTH_LONG);
newToast.show();
}
}
public class MakeOrderActivity extends AppCompatActivity {
Button placeOrderButton;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bundle data = getIntent().getExtras();
int layoutNum = data.getInt("layout");
setContentView(layoutNum);
placeOrderButton = findViewById(R.id.placeOrder);
}
#Override
protected void onStart() {
super.onStart();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.order, menu);
return true;
}
public void onCheckboxClicked(View view){
}
}
Answer is to create a View which is created by getInflator.

I have a problem with my code I develop a game on android studio and I meet the following concern.
There are two buttons on my app, a Punch button and a Kick Button and an Imageview in which I animate my images.
When I click on the punch button, I create a drawable animation of two images
when I click on the kick button, I create a drawable animation of two images as well.
The problem is that when I execute this code with two drawable animations, the application crashes !!
public class MainActivity extends AppCompatActivity {
private Button btnPunch;
private Button btnKick;
private ImageView imageView1 ;
private ImageView imageView2 ;
private AnimationDrawable[] animationDrawable = new
AnimationDrawable[2];
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnPunch = (Button) findViewById(R.id.btnPunch);
imageView1 = (ImageView)
findViewById(R.id.imageView1);
imageView1.setBackgroundResource(
R.drawable.animationpunch);
animationDrawable[0] = (AnimationDrawable)
imageView1.getBackground();
imageView2 = (ImageView)
findViewById(R.id.imageView2);
imageView2.setBackground
Resource(R.drawable.animatio
nkick);
animationDrawable[1] = (AnimationDrawable)
imageView2.getBackground();
btnPunch.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v) {
animationDrawable[1].stop();
animationDrawable[0].setOneShot(true);
animationDrawable[0].start();
}
});
btnKick.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
animationDrawable[0].stop()
animationDrawable[1].setOneShot(true);
animationDrawable[1].start();
}
});
}
#Override
public void onWindowFocusChanged(boolean hasFocus)
{
super.onWindowFocusChanged(hasFocus);
//animationDrawable.start();
}
}
</Code>
I yet use two different imageview for both animations
on the other hand when I remove an animation like the following code, it works well but suddenly I am limited to use the punch button, I would like it to work with both buttons
public class MainActivity extends AppCompatActivity {
private Button btnPunch;
private ImageView imageView1 ;
private AnimationDrawable[] animationDrawable = new
AnimationDrawable[2];
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnPunch = (Button) findViewById(R.id.btnPunch);
imageView1 = (ImageView)
findViewById(R.id.imageView1);
imageView1.setBackground
Resource(R.drawable.animatio
npunch);
animationDrawable[0] = (AnimationDrawable)
imageView1.getBackground();
btnPunch.setOnClickListener(new
View.OnClickListener() {
#Override
public void onClick(View v) {
animationDrawable[1].stop();
animationDrawable[0].setOneShot(true);
animationDrawable[0].start();
}
}}
}
#Override
public void onWindowFocusChanged(boolean hasFocus)
{
super.onWindowFocusChanged(hasFocus);
//animationDrawable.start();
}
}
click on punch button, it animates my animation unch
I click on kick button, it animates my animation kick
a help?
I'm new to Android Studio (and also pretty new to javascrips), so this might be a stupid question.
I do not want to maintain the same code more than once if possible, which is why I am trying to create a navigation-menu, to be used in all my activities.
So far I have created a "BaseActivity" that contains all the functions for my menu. This one works fine.
Now my problem:
In my other activities I can not get it to show up (not without issues anyway). It seems to me like it overwrites the layout.
My base ("BaseActivity"):
public class BaseActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mToggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_base);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
mToggle=new ActionBarDrawerToggle(this, mDrawerLayout, R.string.Open, R.string.Close);
mDrawerLayout.addDrawerListener(mToggle);
mToggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
NavigationView NavigationView=(NavigationView)findViewById(R.id.navigation_view);
NavigationView.setNavigationItemSelectedListener(this);
}
#Override
public void setContentView(int layoutResID)
{
super.setContentView(R.layout.activity_base);
ViewGroup content = (ViewGroup) findViewById(R.id.navigation_view);
getLayoutInflater().inflate(layoutResID, content, true);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if(mToggle.onOptionsItemSelected(item)){
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
int id = item.getItemId();
if(id==R.id.nav_Home) {
startActivity(new Intent(this, MainActivity.class));
}
else
if(id==R.id.nav_Activity1) {
startActivity(new Intent(this, Activity1.class));
}
return super.onOptionsItemSelected(item);
}
}
If I change the app to start through this activity the menu works, but the layout seems to be overwritten (it's empty).
When I try to run it normally (MainActivity), I get some issues.
MainActivity:
public class MainActivity extends BaseActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main); }}
The menu-icon is there, but I can not click on it.
If I remove the code in my MainActivity it works as before (with the layout problem).
I have tried something like this:
public class MainActivity extends BaseActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ViewGroup content = (ViewGroup) findViewById(R.id.navigation_view);
getLayoutInflater().inflate(R.layout.activity_main, content, true);
}}
Not working well. The layout from MainActivity seems to be implemented in the menu. It looks very strange.
Any ideas how to solve my problem?
