我正在开发一个广播接收器,用于Android中的来电和接听来电,我想通过原生来电屏幕弹出一个弹出窗口。
我完成了那段代码。但现在的问题是,Android 4.1 (Jelly Bean) API level 17当电话响铃时,PHONE_STATE
即将发送OFF HOOK
,如果我正在调用某个活动,则会调用它,但是它下面的代码会被调用没有被执行。我列出了代码:
package com.example.popwindowonincomingcallscreen;
import java.util.concurrent.Executors;
import java.util.concurrent.ScheduledExecutorService;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.TelephonyManager;
import android.util.Log;
public class IncomingBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Log.d("IncomingBroadcastReceiver: onReceive: ", "flag1");
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
Log.d("IncomingBroadcastReceiver: onReceive: ", state);
if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)
|| state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) {
Log.d("Ringing", "Phone is ringing");
Intent i = new Intent(context, IncomingCallActivity.class);
i.putExtras(intent);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
Wait.oneSec();
context.startActivity(i);
}
}
}
我正在打电话的活动:
import android.app.Activity;
import android.os.Bundle;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.view.View.MeasureSpec;
import android.view.Window;
import android.view.WindowManager;
import android.widget.TextView;
public class IncomingCallActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
try {
Log.d("IncomingCallActivity: onCreate: ", "flag2");
*/ After this line, the code is not executed in Android 4.1 (Jelly Bean) only/*
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE);
getWindow().addFlags(
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);
Log.d("IncomingCallActivity: onCreate: ", "flagy");
setContentView(R.layout.main);
Log.d("IncomingCallActivity: onCreate: ", "flagz");
String number = getIntent().getStringExtra(
TelephonyManager.EXTRA_INCOMING_NUMBER);
TextView text = (TextView) findViewById(R.id.text);
text.setText("Incoming call from " + number);
}
catch (Exception e) {
Log.d("Exception", e.toString());
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
在
try {
Log.d("IncomingCallActivity: onCreate: ", "flag2");
}
代码没有在Android 4.1(Jelly Bean)中执行,但在其他版本中它正在运行。
我几乎尝试过所有可行的方法。此代码在本机呼叫屏幕上显示半透明活动,并且不会阻止后台控制,例如拿起电话。但我希望它像真正的来电者一样。我附上了真实来电者如何在来电屏幕上显示窗口的快照。
如何为Android应用程序实现此功能?
这是真正的来电者的工作方式:
我现在的输出:
在赏金之后,我也没有得到我想要的东西,但我会回到所有人那里;我正在努力。无论如何,此代码适用于大多数Android手机。如果有人要使用并抓住解决方案,请写在这里以便每个人都可以获得好处。
我尝试在广播接收器的onReceive方法中实现Toast,因为toast是Android的原生组件,但它也没有在Android 4.1(Jelly Bean)中显示。
我的想法是在广播接收器的onReceive方法中实现Toast,然后根据我们的需要改变其设计并调整其显示持续时间。但还有一个问题是 findViewById 在广播接收器中不起作用,所以我认为我们必须以编程方式制作一个LinearLayout来自定义吐司。

我不确定您的自定义GUI将始终位于默认GUI之上,因为系统广播接收器和接收器都试图在屏幕顶部显示其GUI。我们不确定哪一个首先被调用,但是一个棘手的工作是让你的GUI在屏幕上显示是在手机响了1-2秒后使用处理程序为你的活动打电话。
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
Intent intent = new Intent(context, AcceptReject.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
}
}, 2000);
我希望它可以帮助你。

在super.onCreate
方法之前尝试使用代码。我想在调用super之后会跳过代码。有时这种技巧对我有用。

我刚刚在Android 4.2 (Jelly Bean)模拟器上进行了测试,并且通过阻止整个来电屏幕就像truecaller一样完美:
public void onReceive(Context context, Intent intent) {
WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.TYPE_SYSTEM_ALERT |
WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
PixelFormat.TRANSPARENT);
params.height = LayoutParams.MATCH_PARENT;
params.width = LayoutParams.MATCH_PARENT;
params.format = PixelFormat.TRANSLUCENT;
params.gravity = Gravity.TOP;
LinearLayout ly = new LinearLayout(context);
ly.setBackgroundColor(Color.RED);
ly.setOrientation(LinearLayout.VERTICAL);
wm.addView(ly, params);
}
在清单中:
<receiver android:name="" android:enabled="true" >
<intent-filter android:priority="-1">
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>

我也在努力(我在这里理解你可能是错的)。您想要实现的是在Android 4.2(Jelly Bean)中显示该活动。我只是延迟显示活动。我在不同的类中使用过PhoneStateListener。我可以在来电屏幕上显示新活动。这是我的完整代码:
public class MyBroadcastReceiver extends BroadcastReceiver {
static CustomPhoneStateListener phoneStateListener;
Context context;
Intent intent;
@Override
public void onReceive(Context context, Intent intent) {
this.context = context;
this.intent = intent;
// TODO Auto-generated method stub
TelephonyManager telephonyManager = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
phoneStateListener = new CustomPhoneStateListener(context);
telephonyManager.listen(phoneStateListener,
PhoneStateListener.LISTEN_CALL_STATE);
}
}
public class CustomPhoneStateListener extends PhoneStateListener {
// private static final String TAG = "PhoneStateChanged";
Context context; // Context to make Toast if required
private AudioManager amanager;
Intent i1;
public CustomPhoneStateListener(Context context) {
super();
this.context = context;
i1 = new Intent(context, YourActivity.class);
i1.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i1.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
}
@Override
public void onCallStateChanged(int state, String incomingNumber) {
super.onCallStateChanged(state, incomingNumber);
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
Toast.makeText(context, "Phone state Idle", Toast.LENGTH_LONG)
.show();
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
Toast.makeText(context, "Phone state Off hook", Toast.LENGTH_LONG)
.show();
break;
case TelephonyManager.CALL_STATE_RINGING:
try {
Thread.sleep(3000);
context.startActivity(i1);
} catch (Exception e) {
e.getLocalizedMessage();
}
default:
break;
}
}
和YourActivity将保持原样... 注意:我在这里的代码中也遇到了一些问题。
(帮助接受了这些问题。谢谢。可以帮助一些人)

我认为你不应该开始活动来实现所描述的结果。您需要在其布局参数中设置LayoutParams.TYPE_SYSTEM_OVERLAY
的单独视图。
您可以在屏幕上的任何位置放置此视图,或只覆盖整个屏幕。
以下是几行代码:
_av = new ActivatorView(this);
_avLayoutParams = new WindowManager.LayoutParams(0, 0, 0, 0,
WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE,
PixelFormat.OPAQUE);
_avLayoutParams.screenBrightness = _fScreenBrightness = 20f;
WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
wm.addView(_av, _avLayoutParams);

我正在尝试类似的东西,在来电屏幕上添加一个额外的按钮。
Sam Adams发布的答案正在为我工作,虽然我正在调用PhoneStateListener中的代码。除此之外,他的代码唯一真正的区别是我正在夸大布局:
overlay = (RelativeLayout) inflater.inflate(R.layout.overlay, null);
wm.addView(overlay, params);
它正在使用模拟器以及HTC One S(运行Android 4.1.1)。
你需要记住的是保持对你正在添加的覆盖视图的引用,并在手机恢复空闲时(当监听器获取TelephonyManager.CALL_STATE_IDLE时再次将其删除(在windowmanager实例上调用removeView()) ),否则你的叠加层将保留在屏幕上。
WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
if(overlay!=null)
{
wm.removeView(overlay);
overlay = null;
}

我们还面临类似的问题,即叠加没有显示在带锁定的设备上。对我们有用的解决方案如下:
mWindowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
mParams = new LayoutParams(
LayoutParams.MATCH_PARENT,
LayoutParams.WRAP_CONTENT,
LayoutParams.TYPE_SYSTEM_ERROR,
LayoutParams.FLAG_NOT_FOCUSABLE,
PixelFormat.TRANSLUCENT);
LayoutParams.TYPE_SYSTEM_ERROR
是有所作为的。

我的方法:
使用服务制作叠加层
ps:wmParams.type = WindowManager.LayoutParams.TYPE_PHONE;

new Handler().postDelayed(new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
Intent i = new Intent(context, CallingIncoming.class);
i.putExtras(intent);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK /*| Intent.FLAG_ACTIVITY_CLEAR_TASK*/);
context.startActivity(i);
}
}, 450);//It will help you to delay your screen and after it your screen will be top of default app screen

使用简单的广播接收器并将此代码放入广播接收器中:
public void onReceive(final Context context, final Intent intent) {
Log.v(LOG_TAG, "Receieved notification about network status");
WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.TYPE_SYSTEM_ALERT |
WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
PixelFormat.TRANSPARENT);
params.height = WindowManager.LayoutParams.MATCH_PARENT;
params.width = WindowManager.LayoutParams.MATCH_PARENT;
params.format = PixelFormat.TRANSLUCENT;
params.gravity = Gravity.TOP;
LinearLayout ly = new LinearLayout(context);
ly.setBackgroundColor(Color.RED);
ly.setOrientation(LinearLayout.VERTICAL);
wm.addView(ly, params);
}

试试这个
AlertDialog.Builder builder = new AlertDialog.Builder(context.getApplicationContext());
LayoutInflater inflater = LayoutInflater.from(context);
View dialogView = inflater.inflate(R.layout.caller_dialog, null);
ImageView button = dialogView.findViewById(R.id.close_btn);
builder.setView(dialogView);
final AlertDialog alert = builder.create();
alert.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
alert.getWindow().setType(WindowManager.LayoutParams.TYPE_PHONE);
alert.setCanceledOnTouchOutside(true);
alert.show();
WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
Window window = alert.getWindow();
window.addFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);
window.clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
window.setGravity(Gravity.TOP);
lp.copyFrom(window.getAttributes());
//This makes the dialog take up the full width
lp.width = WindowManager.LayoutParams.MATCH_PARENT;
lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
window.setAttributes(lp);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
//close the service and remove the from from the window
alert.dismiss();
}
});
