How do I change the phone call user interface? Like I have my own dialer layout and contacts layout but how do I change the calling UI. So, when the call is going on, can I remove the speaker button for example?
Here is my dialer scene that I have created: Dialer Picture
But I don't know how to edit this screen: Calling Picture
EDIT: I have already built the UI, I just can not get it to show during call!
Here is the code for as a simpler version:
public class MainActivity extends Activity {
private Button callBtn;
private Button dialBtn;
private EditText number;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
number = (EditText) findViewById(R.id.phoneNumber);
callBtn = (Button) findViewById(R.id.call);
dialBtn = (Button) findViewById(R.id.dial);
// add PhoneStateListener for monitoring
MyPhoneListener phoneListener = new MyPhoneListener();
TelephonyManager telephonyManager =
(TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE);
// receive notifications of telephony state changes
telephonyManager.listen(phoneListener,PhoneStateListener.LISTEN_CALL_STATE);
callBtn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
try {
// set the data
String uri = "tel:"+number.getText().toString();
Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse(uri));
startActivity(callIntent);
}catch(Exception e) {
Toast.makeText(getApplicationContext(),"Your call has failed...",
Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
});
dialBtn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
try {
String uri = "tel:"+number.getText().toString();
Intent dialIntent = new Intent(Intent.ACTION_DIAL, Uri.parse(uri));
startActivity(dialIntent);
}catch(Exception e) {
Toast.makeText(getApplicationContext(),"Your call has failed...",
Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
});
}
private class MyPhoneListener extends PhoneStateListener {
private boolean onCall = false;
@Override
public void onCallStateChanged(int state, String incomingNumber) {
switch (state) {
case TelephonyManager.CALL_STATE_RINGING:
// phone ringing...
Toast.makeText(MainActivity.this, incomingNumber + " calls you",
Toast.LENGTH_LONG).show();
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
// one call exists that is dialing, active, or on hold
Toast.makeText(MainActivity.this, "on call...",
Toast.LENGTH_LONG).show();
//because user answers the incoming call
onCall = true;
break;
case TelephonyManager.CALL_STATE_IDLE:
// in initialization of the class and at the end of phone call
// detect flag from CALL_STATE_OFFHOOK
if (onCall == true) {
Toast.makeText(MainActivity.this, "restart app after call",
Toast.LENGTH_LONG).show();
// restart our application
Intent restart = getBaseContext().getPackageManager().
getLaunchIntentForPackage(getBaseContext().getPackageName());
restart.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(restart);
onCall = false;
}
break;
default:
break;
}
}
}
}
Thanks!
Press the Home button and then Tap Use by default for this action. Then Select which interface you would like to use from now on, in this case I Tapped Home.
Add calling permission in manifest
<uses-permission android:name="android.permission.CALL_PHONE" />
Then need to check if call button pressed. for that use below intent filter
<intent-filter>
<action android:name="android.intent.action.CALL_BUTTON" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
and when firing the UI
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<action android:name="android.intent.action.DIAL" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="tel" />
</intent-filter>
that means your calling activity in manifest will be something like this
<activity
android:name="com.example.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<!-- open activity when establishing a call -->
<intent-filter>
<action android:name="android.intent.action.CALL_PRIVILEGED" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="tel" />
</intent-filter>
</activity>
