我正在通过学习Android的过程,我偶然发现了这个问题。
我想做一个“自定义来电屏幕”。我当前的解决方案是一个从BroadcastReceiver扩展的类(IncomingCallInterceptor)。在IncomingCallInterceptor类中,当手机振铃时,我覆盖onReceive并用布局启动我的活动(MainActivity)。
在该活动(MainActivity)中我有三个按钮: 接听电话,挂机,拒绝电话
这些按钮应该按照他们的说法进行操作,接听电话,挂断电话或拒绝接听电话。
我在某种程度上接受了“接听电话”,但没有挂机和拒绝。
下面是我的代码:
清单:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.uppgift.six.one.incoming61.sixone" >
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.CALL_PHONE"/>
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<receiver android:name="IncomingCallInterceptor">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE"/>
</intent-filter>
</receiver>
<activity
android:name=".MainActivity"
android:label="@string/app_name" >
</activity>
</application>
</manifest>
从BroadcastReceiver扩展的IncomingCallInterceptor:
public class IncomingCallInterceptor extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Context appContext = context.getApplicationContext();
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
String msg = "Phone state changed to " + state;
if (TelephonyManager.EXTRA_STATE_RINGING.equals(state)) {
String incomingNumber = intent.getStringExtra
(TelephonyManager.EXTRA_INCOMING_NUMBER);
msg += ". Incoming number is this " + incomingNumber;
//START MY ACTIVITY!
Intent i = new Intent(appContext, MainActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
appContext.startActivity(i);
}
Toast.makeText(context, msg, Toast.LENGTH_LONG).show();
}
}
这是我的活动(布局没什么可发布的,刚才基本上是三个按钮)
public class MainActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btnAnswer = (Button)findViewById(R.id.btnAnswer);
Button btnDecline= (Button)findViewById(R.id.btnDecline);
Button btnHangUp= (Button)findViewById(R.id.btnHangUp);
btnAnswer.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent i = new Intent(Intent.ACTION_MEDIA_BUTTON);
i.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_UP,
KeyEvent.KEYCODE_HEADSETHOOK));
sendOrderedBroadcast(i, null);
}
});
btnDecline.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//Decline Call (I need help here)
}
});
btnHangUp.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//Hang Up Call (I need help here)
}
});
}
在MainActivity类中,它由注释标记,我需要一些帮助。 我也看到了一些关于“Telephonyservice interface”(thingy)解决方案的内容,但我不明白当我测试它时它是如何工作的。
答案 0 :(得分:0)
拒绝来电:
try {
TelephonyManager tm = (TelephonyManager)
getSystemService(Context.TELEPHONY_SERVICE);
try {
Class c = Class.forName(tm.getClass().getName());
Method m = c.getDeclaredMethod("getITelephony");
m.setAccessible(true);
Object telephonyService = m.invoke(tm); // Get the internal ITelephony object
c = Class.forName(telephonyService.getClass().getName()); // Get its class
m = c.getDeclaredMethod("endCall"); // Get the "endCall()" method
m.setAccessible(true); // Make it accessible
m.invoke(telephonyService); // invoke endCall()
} catch (Exception e) {
e.printStackTrace();
}
} catch (Exception e) {
}
}
