悬浮窗口

一、核心代码：

package com.tentinet.testfloatingwinding;import android.content.Intent;import android.graphics.PixelFormat;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.view.Gravity;import android.view.LayoutInflater;import android.view.MotionEvent;import android.view.View;import android.view.WindowManager;import android.widget.ImageView;import android.widget.LinearLayout;import android.widget.Toast;public class MainActivity extends AppCompatActivity {    /** 悬浮框布局*/    private LinearLayout floating_window_layout;    private WindowManager windowManager;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        createFloatingWindow();    }    /**     * 创建悬浮框口     */    private void createFloatingWindow() {        //第一步：加载悬浮框布局        LayoutInflater layoutInflater = this.getLayoutInflater();        floating_window_layout = (LinearLayout) layoutInflater.inflate(R.layout.floating_window_layout,null);        //第二：设置悬浮框属性        final WindowManager.LayoutParams layoutParams = new WindowManager.LayoutParams();        layoutParams.type = WindowManager.LayoutParams.TYPE_PHONE;        layoutParams.format = PixelFormat.RGBA_8888;        layoutParams.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;        layoutParams.gravity = Gravity.LEFT|Gravity.TOP;        layoutParams.x = 60;        layoutParams.y = 60;        layoutParams.width = WindowManager.LayoutParams.WRAP_CONTENT;        layoutParams.height = WindowManager.LayoutParams.WRAP_CONTENT;        //第三步获取本地窗口管理器        windowManager = this.getWindowManager();        //第四步添加布局        windowManager.addView(floating_window_layout, layoutParams);        //第五步：设置触摸移动监听        ImageView img_floating_window = (ImageView) floating_window_layout.findViewById(R.id.img_floating_window);        img_floating_window.setOnTouchListener(new View.OnTouchListener() {            @Override            public boolean onTouch(View v, MotionEvent event) {                layoutParams.x = (int)event.getRawX() - floating_window_layout.getWidth() / 2;                layoutParams.y = (int)event.getRawY() - floating_window_layout.getHeight() / 2;                windowManager.updateViewLayout(floating_window_layout, layoutParams);                return false;            }        });        //第六步：设置点击监听        img_floating_window.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {              /*  Toast.makeText(MainActivity.this,"被点击了",Toast.LENGTH_SHORT).show();*/                startActivity(new Intent(MainActivity.this,TestActivity.class));            }        });    }    @Override    protected void onStop() {        super.onStop();    }    @Override    protected void onDestroy() {        if (floating_window_layout != null){            floating_window_layout.setVisibility(View.GONE);        }        if (windowManager != null){            windowManager.removeView(floating_window_layout);        }        super.onDestroy();    }}

二、floating_window_layout布局：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical"    android:layout_width="60dp"    android:layout_height="60dp">    <ImageView        android:id="@+id/img_floating_window"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:src="@mipmap/ic_launcher"/></LinearLayout>
