Android实现对Dialog的截图并保存在本地

直接上代码:

public class TestDilaog extends Dialog {    public TestDilaog(@NonNull Context context) {        super(context, R.style.UpdateDialogTheme);    }    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.xxxx);        //必须加这两句代码        this.getWindow().getDecorView().setDrawingCacheEnabled(true);        this.getWindow().getDecorView().buildDrawingCache();    }    //将图像保存到SD卡中    public void saveMyBitmap(){        if(!ImageTools.checkSDCardAvailable()){            T.show("SD卡不可用,保存失败");            return;        }        String currentPath= DemoApplication.GalleryPhoto+"/" +System.currentTimeMillis() + ".jpg";        File f = new File(currentPath);        try {            f.createNewFile();        } catch (IOException e) {            // TODO Auto-generated catch block        }        FileOutputStream fOut = null;        try {            fOut = new FileOutputStream(f);        } catch (Exception e) {            e.printStackTrace();        }        //获取bitmap关键代码        View dialogView = this.getWindow().getDecorView();        Bitmap dialogBitmap=dialogView.getDrawingCache();        dialogBitmap.compress(Bitmap.CompressFormat.JPEG, 100, fOut);        try {            fOut.flush();        } catch (IOException e) {            e.printStackTrace();        }        try {            fOut.close();        } catch (IOException e) {            e.printStackTrace();        }        Toast.makeText(context,"图片保存到了"+currentPath,Toast.LENGTH_LONG).show();        MediaScannerConnection.scanFile(context, new String[]{currentPath}, null, null);    }}
