要採取截圖並將其保存到SD卡

Question

在這裏，我想截圖，也保存到SD卡，但我保存失敗。請幫幫我。

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(); 
    } 
} 

在這裏我得到失敗的結果，但我得到了截圖。

Answer 1

你可以試試這個

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

Answer 2

This works perfect, I got my answer. 

view = OnclickView.getRootView(); 

view.setDrawingCacheEnabled(true); 

bitmap = view.getDrawingCache(); 
count++; 
Toast.makeText(MainActivity.this, "count is "+count, Toast.LENGTH_LONG).show(); 

      imageview.setImageBitmap(bitmap); 
      if(count==1) 
      { 
       bitmap = ((BitmapDrawable)imageview.getDrawable()).getBitmap(); 

       ImagePath = MediaStore.Images.Media.insertImage(
       getContentResolver(), 
       bitmap, 
       "demo_image", 
       "demo_image" 
       ); 

       URI = Uri.parse(ImagePath); 

       Toast.makeText(MainActivity.this, "Image Saved Successfully", Toast.LENGTH_LONG).show();
