android悬浮窗权限不用申请,Android WindowManager悬浮窗：不需要申请权限实现悬浮...

package zhangphil.demo;

import android.graphics.Color;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.view.Gravity;

import android.view.View;

import android.view.WindowManager;

import android.widget.TextView;

import android.widget.Toast;public classMainActivity extends AppCompatActivity {

@Overrideprotected voidonCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);//setContentView(R.layout.activity_main);

TextView textView= new TextView(this);

textView.setGravity(Gravity.CENTER);

textView.setBackgroundColor(Color.BLACK);

textView.setText("zhang phil @ csdn");

textView.setTextSize(10);

textView.setTextColor(Color.RED);//类型是TYPE_TOAST，像一个普通的Android Toast一样。这样就不需要申请悬浮窗权限了。

WindowManager.LayoutParams params = newWindowManager.LayoutParams(WindowManager.LayoutParams.TYPE_TOAST);//初始化后不首先获得窗口焦点。不妨碍设备上其他部件的点击、触摸事件。

params.flags =WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;params.width =WindowManager.LayoutParams.MATCH_PARENT;params.height = 300;//params.gravity=Gravity.BOTTOM;

textView.setOnClickListener(newView.OnClickListener() {

@Overridepublic voidonClick(View v) {

Toast.makeText(getApplication(),"不需要权限的悬浮窗实现", Toast.LENGTH_LONG).show();

}

});

WindowManager windowManager=(WindowManager) getApplication().getSystemService(getApplication().WINDOW_SERVICE);

windowManager.addView(textView,params);

}

}
