【问题描述】：
我正在制作一个随叫随到的 Dialer 应用程序演示，我已经成功地完成了传入和传出功能。现在我的问题是我想在呼叫被拒绝或断开连接时更改活动。我已经尝试了很多东西，也挖掘了很多链接。任何人都可以帮助我如何在通话断开时切换屏幕。我的 call_state 接收器如下：
package com.example.dialingdemo;
import Utils.Const;
import Utils.Pref;
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Handler;
import android.provider.CallLog;
import android.telephony.TelephonyManager;
import android.widget.Toast;
public class MyCallReceiver extends BroadcastReceiver {
@Override
public void onReceive(final Context context, final Intent intent) {
if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
final String savedNumber = intent.getExtras().getString(
"android.intent.extra.PHONE_NUMBER");
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
Intent i = new Intent(context, CallScreen.class);
i.putExtra("incomingNumber", savedNumber);
i.putExtras(intent);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
i.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
context.startActivity(i);
Toast.makeText(context, "OUTGOING CAL to : " + savedNumber,
Toast.LENGTH_LONG).show();
}
}, 1000);
}
else if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(
TelephonyManager.EXTRA_STATE_RINGING)) {
final String incomingNumber = intent
.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
Toast.makeText(context, "Call from:" + incomingNumber,
Toast.LENGTH_LONG).show();
new Handler().postDelayed(new Runnable() {
public void run() {
Intent i = new Intent(context, IncomingCall.class);
i.putExtra("incomingNumber", incomingNumber);
i.putExtras(intent);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
i.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
context.startActivity(i);
}
}, 1000);
} else if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(
TelephonyManager.EXTRA_STATE_IDLE)
|| intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(
TelephonyManager.EXTRA_STATE_OFFHOOK)) {
// This code will execute when the call is disconnected
if (Const.call_state.equals("1")) {
new Handler().postDelayed(new Runnable() {
public void run() {
Intent i = new Intent(context, CallScreen.class);
i.putExtras(intent);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
i.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
context.startActivity(i);
}
}, 1000);
} else if (Const.call_state.equals("2")) {
new Handler().postDelayed(new Runnable() {
public void run() {
Intent i = new Intent(context, CallScreen.class);
i.putExtras(intent);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
i.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
context.startActivity(i);
}
}, 1000);
}
}
}
}
