如何让android中的应用程序每隔五分钟捕获一次屏幕？

Answer 1

尝试以下代码屏幕截图： -

// image naming and path  to include sd card  appending name you choose for file
String mPath = Environment.getExternalStorageDirectory().toString() + "/" + ACCUWX.IMAGE_APPEND;   

// create bitmap screen capture
Bitmap bitmap;
View v1 = mCurrentUrlMask.getRootView();
v1.setDrawingCacheEnabled(true);
bitmap = Bitmap.createBitmap(v1.getDrawingCache());
v1.setDrawingCacheEnabled(false);

OutputStream fout = null;
imageFile = new File(mPath);

try {
    fout = new FileOutputStream(imageFile);
    bitmap.compress(Bitmap.CompressFormat.JPEG, 90, fout);
    fout.flush();
    fout.close();

} catch (FileNotFoundException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

每5分钟捕获

private final static int INTERVAL = 1000 * 60 * 5; //5 minutes
Handler m_handler;

Runnable m_handlerTask = new Runnable()
{
     @Override 
     public void run() {
          doSomething();// call your screen shot method
          m_handler.postDelayed(m_handlerTask, INTERVAL);
     }
}

void startRepeatingTask()
{
    m_handlerTask.run(); 
}

void stopRepeatingTask()
{
    m_handler.removeCallback(m_handlerTask);
}

使用此代码：

boolean workDone = false;
final static int ROUNDTRIP_TIMOUT = 5*60*1000;
private boolean timeout() {
        int waited = 0;
        while (waited < ROUNDTRIP_TIMOUT) {
            try {
                Thread.sleep(100);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            waited += 100;
            if (waited == ROUNDTRIP_TIMOUT) {
                captureScreen();
                workDone = true;
            }
        }
        return workDone;
    }

    public void captureScreen()
    {
        // create bitmap screen capture
        Bitmap bitmap;
        View v1 = mCurrentUrlMask.getRootView();
        v1.setDrawingCacheEnabled(true);
        bitmap = Bitmap.createBitmap(v1.getDrawingCache());
        v1.setDrawingCacheEnabled(false);
    }

    if(timeout())
         Log.v(TAG , "Screen Capture");
    else
        Log.v(TAG , "Not Done");
