推荐答案

让我们说你点击一个按钮：

Let's say that you clicked on a button:

findViewById(R.id.button1).setOnClickListener(new OnClickListener() {
   @Override
   public void onClick(View v) {
       Bitmap bitmap = takeScreenshot();
       saveBitmap(bitmap);
   }
});

在您需要这两种方法：

public Bitmap takeScreenshot() {
   View rootView = findViewById(android.R.id.content).getRootView();
   rootView.setDrawingCacheEnabled(true);
   return rootView.getDrawingCache();
}

 public void saveBitmap(Bitmap bitmap) {
    File imagePath = new File(Environment.getExternalStorageDirectory() + "/screenshot.png");
    FileOutputStream fos;
    try {
        fos = new FileOutputStream(imagePath);
        bitmap.compress(CompressFormat.PNG, 100, fos);
        fos.flush();
        fos.close();
    } catch (FileNotFoundException e) {
        Log.e("GREC", e.getMessage(), e);
    } catch (IOException e) {
        Log.e("GREC", e.getMessage(), e);
    }
}
