每当我点击“截屏”按钮时，它就会卡住并继续拍摄截图。

停止按钮

此按钮的功能是停止线程并停止代码截取屏幕截图。

Thread th = new Thread(new Runnable() {
    @Override
    public void run() {
        StopThread.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                thread.interrupt();
                check=false;
                //textView.setText(TotalShots);
            }
        });
    }
});
th.start();

选择ScreenShot按钮

此按钮的功能是启动线程并开始截屏。

public void screenShot(View view) throws IOException {
        thread = new Thread(new Runnable() {
            @Override
            public void run() {
                    runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                            if (!Thread.interrupted()){

                                while (check)
                                {
                                    captureScreenShot = (Button) findViewById(R.id.capture_screen_shot);
                                    c = Calendar.getInstance();
                                    SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
                                    name = simpleDateFormat.format(c.getTime());
                                    mbitmap = getBitmapOFRootView(captureScreenShot);
                                    imageView.setImageBitmap(mbitmap);
                                    try {
                                        createImage(mbitmap);
                                    } catch (IOException e) {
                                        e.printStackTrace();
                                    }


                                }
                            }

                        }
                    });
            }
        });
        thread.start();
    }

无需启动线程或类似按钮单击即可轻松调用方法。而不是设置比imageview内的位图或任何你想要使用的位图。

volatile boolean flag = true;

public void run() 
{
while(flag)
    {    
   // Do your task of calling method of screenshot
    try{
        Thread.Sleep(interval);
    } catch(Exception e){

        }

    }
}

单击停止按钮时将标志设置为false。

public Bitmap takeScreenShot(View view) {

// configuramos para que la view almacene la cache en una imagen
view.setDrawingCacheEnabled(true);
view.setDrawingCacheQuality(View.DRAWING_CACHE_QUALITY_LOW);
view.buildDrawingCache();

if(view.getDrawingCache() == null) return null; // Verificamos antes de que no sea null

// utilizamos esa cache, para crear el bitmap que tendra la imagen de la view actual
Bitmap snapshot = Bitmap.createBitmap(view.getDrawingCache());
view.setDrawingCacheEnabled(false);
view.destroyDrawingCache();

return snapshot;
}
