弹出像truecaller来电屏幕上的窗口 [英] popup window on incoming call screen like truecaller
问题描述
我试图来电屏幕上添加弹出窗口，真正的来电，但未能实现。让我知道了什么是这背后的逻辑，以及如何，我可以实现这个
公共无效的onReceive（上下文的背景下，意图意图）{
尝试 {
//注册一个听者电话管理器类对象
TelephonyManager TMGR =（TelephonyManager）上下文
.getSystemService（Context.TELEPHONY_SERVICE）;
}
}赶上（例外五）{
Log.e（手机接收错误，+ E）;
}
}
我用下面的方法对我的应用程序，其中我想表明一个观点ontop当它启动（类似的东西，在Truecaller）的拨号器应用程序的。为此，创建一个广播接收器，这有助于接受各种设备事件，如下所述。
广播接收器
专用窗口管理WM;
私有静态的LinearLayout LY1;
私人WindowManager.LayoutParams params1;
//广播接收器的onReceive功能
公共无效的onReceive（背景为arg0，意图ARG1）{
字符串状态= arg1.getStringExtra（TelephonyManager.EXTRA_STATE）;
//添加就可以了启动时的拨号器应用程序的顶部视图。
如果（state.equals（TelephonyManager.EXTRA_STATE_OFFHOOK））{
WM =（窗口管理器）context.getSystemService（Context.WINDOW_SERVICE）;
params1 =新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）;
params1.height = 75;
params1.width = 512;
params1.x = 265;
params1.y = 400;
params1.format = PixelFormat.TRANSLUCENT;
LY1 =新的LinearLayout（上下文）;
ly1.setBackgroundColor（Color.BLACK）;
ly1.setOrientation（LinearLayout.VERTICAL）;
wm.addView（LY1，params1）;
}
//要删除的看法，一旦拨号应用程序被关闭。
如果（arg1.getAction（）。等于（android.intent.action.PHONE_STATE））{
字符串状态= arg1.getStringExtra（TelephonyManager.EXTRA_STATE）;
如果（state.equals（TelephonyManager.EXTRA_STATE_IDLE））{
窗口管理WM =（窗口管理器）context.getSystemService（Context.WINDOW_SERVICE）;
如果（LY1！= NULL）
{
wm.removeView（LY1）;
LY1 = NULL;
}
}
}
}
PS ：以上如发生具有黑色背景的布局视图，其尺寸如图所示above.You有自由在这个view.For如添加任何布局：要包括布局在视图中，你可以修改上面的code，包括以下内容：
LY1 =新的LinearLayout（getApplicationContext（））;
ly1.setOrientation（LinearLayout.HORIZONTAL）;
查看hiddenInfo = getLayoutInflater（）膨胀（R.layout.layout1，LY1，假的）。
ly1.addView（hiddenInfo）;
wm.addView（LY1，params1）;
PS ：布局1是你需要创建布局文件夹，并在这里引用一个布局
Addtionally ，在你的清单，你需要包括以下权限。
＆LT;使用-权限的Android：名称=android.permission.SYSTEM_ALERT_WINDOW＆GT;＆LT; /使用-许可＆GT;
＆LT;使用-权限的Android：名称=android.permission.READ_PHONE_STATE/＆GT;
＆LT;使用-权限的Android：名称=android.permission.MODIFY_PHONE_STATE/＆GT;
＆lt;作用机器人：名称=android.intent.action.PHONE_STATE/＆GT; （在广播接收机的意图过滤器）
i am trying to add popup window on incoming call screen as true caller but fail to implement .let me know what is logic behind this and how i can implement this
public void onReceive(Context context, Intent intent) {
try {
// TELEPHONY MANAGER class object to register one listner
TelephonyManager tmgr = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
}
} catch (Exception e) {
Log.e("Phone Receive Error", " " + e);
}
}
I have used the below approach for my app,wherein I wanted to show a view ontop of the Dialer app when it launches(something similar to that in Truecaller).For this,create a Broadcast Receiver which helps to accept various device events as described below.
Broadcast Receiver :
private WindowManager wm;
private static LinearLayout ly1;
private WindowManager.LayoutParams params1;
// onReceive function of the Broadcast Receiver
public void onReceive(Context arg0, Intent arg1) {
String state = arg1.getStringExtra(TelephonyManager.EXTRA_STATE);
// Adds a view on top of the dialer app when it launches.
if(state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)){
wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
params1 = 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);
params1.height = 75;
params1.width = 512;
params1.x = 265;
params1.y = 400;
params1.format = PixelFormat.TRANSLUCENT;
ly1 = new LinearLayout(context);
ly1.setBackgroundColor(Color.BLACK);
ly1.setOrientation(LinearLayout.VERTICAL);
wm.addView(ly1, params1);
}
// To remove the view once the dialer app is closed.
if(arg1.getAction().equals("android.intent.action.PHONE_STATE")){
String state = arg1.getStringExtra(TelephonyManager.EXTRA_STATE);
if(state.equals(TelephonyManager.EXTRA_STATE_IDLE)){
WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
if(ly1!=null)
{
wm.removeView(ly1);
ly1 = null;
}
}
}
}
PS: The above eg generated a view having a layout with black background,having dimension as shown above.You have the liberty to add any layout within this view.For eg :To include a layout within the view you can modify the above code to include the following:
ly1 = new LinearLayout(getApplicationContext());
ly1.setOrientation(LinearLayout.HORIZONTAL);
View hiddenInfo = getLayoutInflater().inflate(R.layout.layout1, ly1, false);
ly1.addView(hiddenInfo);
wm.addView(ly1, params1);
PS: Layout1 is a layout which you need to create in your layout folder and reference it here.
Addtionally , in your manifest you need to include the following permissions.
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"></uses-permission>
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.MODIFY_PHONE_STATE" />
<action android:name="android.intent.action.PHONE_STATE" /> (within intent filter of Broadcast Receiver)
