Question

I am trying to setup a simple mute button on the GUI of my app. Which when selected:
1. mutes the Media Volume
an when selected again,
2. unmutes the Media Volume

I am new to Java. I don’t know what bundle to import or which statement is best for this.
Here’s what I have so far:

//Mute Button
    btnMute = (Button)findViewById(R.id.wmute);

Button XML:

<Button
        android:id="@+id/wmute"
        style="?android:attr/buttonStyleSmall"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Mute" />

Answer 1

selected: 1

@Override
   public void onClick(View v) {

      switch (v.getId()) {
      case R.id.wmute:
        AudioManager.setMode(AudioManager.MODE_IN_CALL);
        AudioManager.setStreamSolo(AudioManager.STREAM_VOICE_CALL, true);
         break;
      default:
         break;
      }

   }

selected: 2

AudioManager.setMode(AudioManager.MODE_NORMAL );
AudioManager.setStreamSolo(AudioManager.STREAM_VOICE_CALL, false);
