我试图添加弹出式窗口的来电屏幕作为真正的呼叫者，但未能实现.let我知道这是什么逻辑背后，我可以如何实现这一点
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);
}

尝尝这个
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();
}
});并在您的onCreate()中添加权限检查
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && !Settings.canDrawOverlays(getActivity())) {
//If the draw over permission is not available open the settings screen
//to grant the permission.
Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
Uri.parse("package:" + getActivity().getPackageName()));
startActivityForResult(intent, CODE_DRAW_OVER_OTHER_APP_PERMISSION);
}和onActivityResult()
private static final int CODE_DRAW_OVER_OTHER_APP_PERMISSION = 2084;
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CODE_DRAW_OVER_OTHER_APP_PERMISSION) {
//Check if the permission is granted or not.
if (resultCode == RESULT_OK) {
}
else
{
// Permission is not available
}
} else {
super.onActivityResult(requestCode, resultCode, data);
}
}并且不要忘记在清单中添加权限
