i looking to fill the blank space when ads not showing in my app.
the ads are working fine and showing when i'am connected with internet.
but when the phone is not connected with sure the ad won't show up
so the ads space become blank.
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<com.google.android.gms.ads.AdView android:id="#+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
ads:adUnitId="ca-app-pub-xxxxxxxxxxxxxxxxxxxxxxxx"
ads:adSize="BANNER"/>
<TabWidget
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#android:id/tabs"
/>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</FrameLayout>
</LinearLayout>
You can try this:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
AdView adView = (AdView)this.findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
adView.loadAd(adRequest);
adView.setAdListener(new AdListener() {
public void onAdFailedToLoad(int errorcode) {}
adView.setVisibility(View.GONE);
});
}

I've created a stopwatch app when the user clicks the Lap button just gives the current time the timer is at. My problem is text in ListView displays at the left corner. I'm finding it impossible to center the text in my listview. Here I attached my XML and Java code.
activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_margin="100dp"
android:text="format"
android:textSize="40dp"
android:textStyle="bold" />
<Button
android:id="#+id/start"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginLeft="110dp"
android:text="Start" />
<Button
android:id="#+id/reset"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginLeft="20dp"
android:layout_toRightOf="#id/start"
android:text="Reset" />
<ListView
android:id="#+id/listview1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/start"

MainActivity.java:
public class MainActivity extends AppCompatActivity
{
TextView time;
Button reset, start;
ListView listView;
long startTime, TimeBuff, millisecondsTime, UpdateTime = 0L;
int seconds, milliseconds, minutes;
Handler handler;
List<String> ListElementsArrayList;
ArrayAdapter<String> adapter;
String[] ListElements = new String[]{};///creating arrays of string type
#Override
protected void onCreate(final Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
time = (TextView) findViewById(R.id.textView);
start = (Button) findViewById(R.id.start);
reset = (Button) findViewById(R.id.reset);
listView = (ListView) findViewById(R.id.listview1);
handler = new Handler();
//Getting the list of array
ListElementsArrayList = new ArrayList<String>(Arrays.asList(ListElements));
adapter = new ArrayAdapter<String>(MainActivity.this,
android.R.layout.simple_list_item_1,
ListElementsArrayList);
listView.setAdapter(adapter);
}
}
To do it You have to create a layout in Your res/layout folder. With name e.g. list_item_layout.xml. In this layout add this:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:textSize="20sp" />
In this file, You can make custom TextView which You want to display (change font, size etc.). To center text use android:gravity="center"
Next, when You create an ArrayAdapter, use this layout:
adapter = new ArrayAdapter<String>(
MainActivity.this,
R.layout.list_item_layout, // here You use created layout
ListElementsArrayList
);

I have a question regarding android layouts. I cannot achieve what I am looking for and I need some direction.
I am looking for a layout that will be inside a Scroll View layout. its hard to explain but a picture is worth thousand words.enter image description here
I want this inside a scroll view, can any help please?
If you do not want to add images dynamically than this is the layout you want Try this.

Here i am attaching screenshot of this layout UI.
Try this,I have made two layouts ..
1) activity_main that contains gridview and webview.
2)activity_gridview which contains imageview which will inflate in gridview.
I have added images dynamically to Gridview using BaseAdapter.
In MainActivity i have set that Adapter to GridView. Try this code once.
activity_main.xml :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ScrollView
android:id="#+id/scrollView"

android:layout_height="match_parent"
android:orientation="horizontal">
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/grid"
android:layout_width="100dp"
android:layout_height="match_parent"
android:numColumns="1"></GridView>
<WebView
android:id="#+id/webView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_toRightOf="#id/linImages"></WebView>
</LinearLayout>
</ScrollView>
</RelativeLayout>
activity_gridview.xml :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView

android:layout_width="100dp"
android:layout_height="100dp"

<ImageView
android:id="#+id/imgView4"
android:layout_width="100dp"
android:layout_height="100dp"
android:background="#drawable/star1" />
</LinearLayout>
CustomAdapter.java :
public class CustomAdapter extends BaseAdapter {
Context context;
int flags[];
LayoutInflater inflter;
public CustomAdapter(Context applicationContext, int[] flags) {
this.context = applicationContext;
this.flags = flags;
inflter = (LayoutInflater.from(applicationContext));
}
#Override
public int getCount() {
return flags.length;
}
#Override
public Object getItem(int i) {
return null;
}
#Override
public long getItemId(int i) {
return 0;
}
#Override
public View getView(int i, View view, ViewGroup viewGroup) {
view = inflter.inflate(R.layout.activity_gridview, null);
ImageView imgView1 = (ImageView) view.findViewById(R.id.imgView1);
ImageView imgView2 = (ImageView) view.findViewById(R.id.imgView2);
ImageView imgView3 = (ImageView) view.findViewById(R.id.imgView3);
ImageView imgView4 = (ImageView) view.findViewById(R.id.imgView4);
imgView1.setImageResource(flags[0]);
imgView2.setImageResource(flags[1]);
imgView3.setImageResource(flags[2]);
imgView4.setImageResource(flags[3]);
return view;
}
}
MainActivity.java :
public class MainActivity extends AppCompatActivity {
int images[] = {R.drawable.star2, R.drawable.star1, R.drawable.star3, R.drawable.star1};
GridView grid;
CustomAdapter customAdapter;
WebView webView;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

How can I make a radio button group and a TextField, so that whenever I click on TextField the radio button automatically changes from one to another?
Please give me a block of code for this.
If I understood your question correctly, you want the radioButton checked status change once the textView click. You can achieve by this way.
public class MainActivity extends Activity {
private RadioGroup radioSexGroup;
private RadioButton radioSexButton,male,female;
private TextView btnDisplay;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
radioSexGroup=(RadioGroup)findViewById(R.id.radioGroup);
btnDisplay=(TextView)findViewById(R.id.textView3);
male = (RadioButton)findViewById(R.id.radioButton);
female=(RadioButton)findViewById(R.id.radioButton2);
btnDisplay.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int selectedId=radioSexGroup.getCheckedRadioButtonId();
radioSexButton=(RadioButton)findViewById(selectedId);
if(radioSexButton.getText().toString().equals("Male"))
{
female.setChecked(true);
}
else
{
male.setChecked(true);
}
}
});
}
}

Audio is played when the user selects an item from the list, i have three buttons one is to stop the playing audio and the other two are one to play the next item on the list and one to play the previous
How would i achieve this? i have made the buttons to be clickable and then i try writing the code eg. mp.stop(); to stop the music but this is not working? and also how would i get the other buttons to play next and previous items on the list?
Below is my .java file
public class Nasheeds extends ListActivity {
//ArrayList holds the data (as HashMaps) to load into the ListView
ArrayList<HashMap<String,String>> list = new ArrayList<HashMap<String,String>>();
//SimpleAdapter does the work to load the data in to the ListView
private SimpleAdapter sa;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.nasheeds2);
//HashMap links each line of data to the correct TextView
HashMap<String,String> item;
for(int i=0;i<Nasheed.length;i++){
item = new HashMap<String,String>();
item.put( "line1", Nasheed[i][0]);
item.put( "line2", Nasheed[i][1]);
list.add( item );
}
sa = new SimpleAdapter(this, list,
R.layout.nasheeds1,
new String[] { "line1","line2" },
new int[] {R.id.displayname, R.id.title});
setListAdapter(sa);
getListView().setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
switch (arg2)
{
case 0:
System.out.println("User selected option 1");
MediaPlayer mp = MediaPlayer.create(Nasheeds.this, R.raw.mok);
mp.start();
TextView tv=(TextView) findViewById(R.id.selectedfile);
tv.setText("Playing "+ "Mountains of Mekkah, Zain Bikha");
break;
case 1:
System.out.println("User selected option 2");
case 2:
break;
}
}
});
}
private String[][] Nasheed =
{{"Mountains of Mekkah","Zain Bikha"},
{"Hadith 2","....add hadith...."},
{"Hadith 3",".....add hadith"},};
}
and this is my one of the nasheed2.xml file:
<ListView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#android:id/list"
android:layout_weight="1.0"

<TextView
android:id="#+id/songTotalDurationLabel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" />
</LinearLayout>
</LinearLayout>
this is the other nasheed1.xml file:
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/displayname"
android:textSize="18dip"
android:textStyle="bold"

android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/title"
android:textSize="15dip"
android:singleLine="true"
android:ellipsize="end"
android:layout_weight="1.0"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/duration"
android:gravity="right"
android:textSize="15dip"
android:singleLine="true"
android:ellipsize="end"/>
</LinearLayout>
</LinearLayout>
Try this below code on play button click event.
public boolean istrue = true;
btnplay.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (istrue) {
mp.pause();
istrue = false;
} else {
mp.start();
istrue = true;
}
}
});
or create one other button for stop audio.
on click that stop button use this
mp.stop();

You can get the size of the phone with this code:
DisplayMetrics metrics = new DisplayMetrics();
((Activity)c).getWindowManager().getDefaultDisplay().getMetrics(metrics);
screenWidth = ((int)metrics.xdpi);
screenHeight = ((int)metrics.ydpi);
You can use setPadding and the width and height of the phone can be got by the code above. I had positioning problems too and this was the solution.
