Audio starts on list item click how to stop? - android-layout

Question

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"
/>
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"

android:padding="10dip">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/selectedfile"
android:text="Not file selected"
android:textColor="#android:color/black"
android:gravity="center_horizontal"
android:singleLine="true"
android:ellipsize="middle"/>

android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:background="#android:drawable/screen_background_light">
<TextView

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" />
<ImageButton

android:layout_height="wrap_content"
android:id="#+id/prev"
android:src="#android:drawable/ic_media_previous"
android:onClick="doClick"/>

<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:ellipsize="end"/>
<LinearLayout

android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
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>

Answer 1

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();
