Java 每次拍摄屏幕截图以显示图像到图像查看器应用程序

我有截图按钮，当我拍摄截图时，图像应该存储在sd卡中，当我去看画廊时，他们会显示图像

但是，我想在每次拍摄截图时，在图像查看器应用程序中显示

我的代码在这里：

public class MainActivity extends Activity {

Button captureImage;    
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    captureImage = (Button)findViewById(R.id.captureImage);       
    captureImage.setOnClickListener(new View.OnClickListener() {        
        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub
             Bitmap bitmap = takeScreenshot();
             saveBitmap(bitmap);    
        }

        private void saveBitmap(Bitmap bitmap) {
            // TODO Auto-generated method stub
             File imagePath = new File(Environment.getExternalStorageDirectory() + "/DCIM/Camera/"+"MyProfile.JPEG");
              sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,Uri.fromFile(imagePath)));
              FileOutputStream fos;
              try {
                  fos = new FileOutputStream(imagePath);
                  bitmap.compress(CompressFormat.JPEG, 100, fos);
                  fos.flush();
                  fos.close();
                  Toast.makeText(getApplicationContext(), "Screen short saved", Toast.LENGTH_SHORT).show();
              } catch (FileNotFoundException e) {
                 Toast.makeText(getApplicationContext(), "File not found", Toast.LENGTH_SHORT).show();
              } catch (IOException e) {
                  Toast.makeText(getApplicationContext(), "something wrong", Toast.LENGTH_SHORT).show();
              }
        }
        private Bitmap takeScreenshot() {
            // TODO Auto-generated method stub
            View rootView = findViewById(android.R.id.content).getRootView();
               rootView.setDrawingCacheEnabled(true);
               return rootView.getDrawingCache();
        }
    });
}    

清单

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

屏幕截图：

public class MainActivity extends Activity {

Button captureImage;    
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    captureImage = (Button)findViewById(R.id.captureImage);       
    captureImage.setOnClickListener(new View.OnClickListener() {        
        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub
             Bitmap bitmap = takeScreenshot();
             saveBitmap(bitmap);    
        }

        private void saveBitmap(Bitmap bitmap) {
            // TODO Auto-generated method stub
             File imagePath = new File(Environment.getExternalStorageDirectory() + "/DCIM/Camera/"+"MyProfile.JPEG");
              sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,Uri.fromFile(imagePath)));
              FileOutputStream fos;
              try {
                  fos = new FileOutputStream(imagePath);
                  bitmap.compress(CompressFormat.JPEG, 100, fos);
                  fos.flush();
                  fos.close();
                  Toast.makeText(getApplicationContext(), "Screen short saved", Toast.LENGTH_SHORT).show();
              } catch (FileNotFoundException e) {
                 Toast.makeText(getApplicationContext(), "File not found", Toast.LENGTH_SHORT).show();
              } catch (IOException e) {
                  Toast.makeText(getApplicationContext(), "something wrong", Toast.LENGTH_SHORT).show();
              }
        }
        private Bitmap takeScreenshot() {
            // TODO Auto-generated method stub
            View rootView = findViewById(android.R.id.content).getRootView();
               rootView.setDrawingCacheEnabled(true);
               return rootView.getDrawingCache();
        }
    });
}    

我需要像这样出去

我不明白你需要什么。是否要在ImageView上显示结果？您可以这样做：

imageView.setImageBitmap（位图）完美存储并显示在图像到图像视图中。我所需要的意思是，当我缩短屏幕时，我想显示图像查看器。图像查看器-只有默认的移动图像查看器。
