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>
