Java 如何在手机铃声响起时查看

我想自定义手机铃声视图并显示和显示文本视图。现在我如何访问该视图并自定义它？或者，如果我无法访问它，我可以为在该视图中显示文本视图做些什么

您需要创建一个应用程序，并在活动中扩展BroadcastListener服务，并为该活动提供所需的布局 1） 在AndroidManifest.xml中声明广播接收器

     <receiver android:name=".MainActivity">   
            <intent-filter>
               <action android:name="android.intent.action.PHONE_STATE" />
            </intent-filter>
    </receiver>

}

此代码将在接到电话时显示toast，您可以根据需要更改布局文件和显示。

其当前活动的上下文，只需将“pcontext”替换为“getApplicationContext（）”或“您的活动名称”。此

    <uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>

    public class MainActivity extends BroadcastReceiver {

public void onReceive(Context context, Intent intent) {

try {
           // TELEPHONY MANAGER class object to register one listner
            TelephonyManager tmgr = (TelephonyManager) context
                    .getSystemService(Context.TELEPHONY_SERVICE);

            //Create Listner
            MyPhoneStateListener PhoneListener = new MyPhoneStateListener();

            // Register listener for LISTEN_CALL_STATE
            tmgr.listen(PhoneListener, PhoneStateListener.LISTEN_CALL_STATE);

    } catch (Exception e) {
        Log.e("Phone Receive Error", " " + e);
    }

}

private class MyPhoneStateListener extends PhoneStateListener {
    public void onCallStateChanged(int state, String incomingNumber) {

        Log.d("MyPhoneListener",state+"   incoming no:"+incomingNumber);

        if (state == 1) {

            String msg = "New Phone Call Event. Incomming Number : "+incomingNumber;
            int duration = Toast.LENGTH_LONG;
            Toast toast = Toast.makeText(pcontext, msg, duration);
            toast.show();

        }
    }
}
