Question

这里我试图截取屏幕并保存到SD卡但我在保存时失败了。请帮帮我。

 public void onClick(View OnclickView) {
     boolean success = false;
     view = OnclickView.getRootView();
     view.setDrawingCacheEnabled(true);
     bitmap = view.getDrawingCache();
     ScreenShotHold.setImageBitmap(bitmap);
     bitmap.compress(Bitmap.CompressFormat.PNG, 60, bytearrayoutputstream);
     File sdCardDirectory = Environment.getExternalStorageDirectory();
     File image = new File(sdCardDirectory, "test.png");
     boolean success = false;
     // Encode the file as a PNG image.
     FileOutputStream outStream;
     try {
         outStream = new FileOutputStream(image);
         bitmap.compress(Bitmap.CompressFormat.PNG, 100, outStream);
         Toast.makeText(getApplicationContext(), "bitmap " + bitmap, Toast.LENGTH_SHORT).show();
         Toast.makeText(getApplicationContext(), "outstream " + outStream, Toast.LENGTH_SHORT).show();
         /* 100 to keep full quality of the image */
         outStream.flush();
         outStream.close();
         success = true;
     } catch (FileNotFoundException e) {
         e.printStackTrace();
     } catch (IOException e) {
         e.printStackTrace();
     }
     if (success == true) {
         Toast.makeText(getApplicationContext(), "Saved", Toast.LENGTH_SHORT).show();
     } else {
         Toast.makeText(getApplicationContext(), "Failed", Toast.LENGTH_SHORT).show();
     }
 }

我在这里收到失败的结果，但我正在截图。

Answer 1

你可以试试这个

Bitmap screenshotedBitmap = yourBitmap;
String lastInsertedPath =  MediaStore.Images.Media.insertImage(getContentResolver(), screenshotedBitmap, "myImage", "modified image");

Answer 2

DECLARE @query varchar(max),
@col  varchar(250) = 'd1,d2,d3'


Set @query = 'INSERT INTO [dbo].[MYTABLE](
                   '+@col+'
                   )
                   SELECT  ''~N'' AS ['+@col+']'
print @query
