标签: android screenshot

我从这里跟随@Mualig回答:How to programmatically take a screenshot in Android? 我没有收到任何错误消息,我的打印行似乎表明正在创建文件(文件夹),图像也是如此,并且正在保存。但是,此文件未显示。 任何人都可以解释原因吗?

 file = new File(Environment.getExternalStorageDirectory() + "/M");
      if(!file.exists())//check if file already exists
      {
          file.mkdirs();//if not, create it
          System.out.println("File Created");
      }


    Button button = (Button)findViewById(R.id.btnTakeScreenshot);
      button.setOnClickListener(new View.OnClickListener() {
          public void onClick(View v) {



              String mPath = Environment.getExternalStorageDirectory().toString() + "/M/image.JPG";   

              System.out.println(mPath);
              // create bitmap screen capture
              Bitmap bitmap;
              View v1 = getWindow().getDecorView().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();
              }
        }
        });
