将拍摄的图片从ImageView存储到手机存储中

Question

After I take a picture I store the picture into ImageView, So if anyone has an idea or suggestion in how to store the picture after it shown on the ImageView into phone stage without user interaction Thanks in advance

public class MainActivity extends Activity {
    ImageView viewpict;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        viewpict=(ImageView) findViewById(R.id.pict_result);
        Button btn= (Button)findViewById(R.id.camera);

        btn.setOnClickListener(new OnClickListener(){

            @Override
            public void onClick(View arg0) {
                Intent intent = new Intent (android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            //  Intent intent = new Intent (getApplicationContext(),MainActivity2.class);

                //startActivity(intent);
                startActivityForResult(intent,0);

            }

     });


    }

protected void onActivityResult( int requestCode, int resultCode,Intent data)
{
    if (requestCode==0)
    {
        Bitmap theimage = (Bitmap) data.getExtras().get("data");
        viewpict.setImageBitmap(theimage);
    }

}

}

Try:

viewpict.buildDrawingCache();
Bitmap bm=viewpict.getDrawingCache();

And save:

 OutputStream fOut = null;
    Uri outputFileUri;
     try {
    File root = new File(Environment.getExternalStorageDirectory()
      + File.separator + "folder_name" + File.separator);
    root.mkdirs();
   File sdImageMainDirectory = new File(root, "myPicName.jpg");
    outputFileUri = Uri.fromFile(sdImageMainDirectory);
    fOut = new FileOutputStream(sdImageMainDirectory);
   } catch (Exception e) {
    Toast.makeText(this, "Error occured. Please try again later.",
      Toast.LENGTH_SHORT).show();
   }

   try {
    bm.compress(Bitmap.CompressFormat.PNG, 100, fOut);
    fOut.flush();
    fOut.close();
   } catch (Exception e) {
   }

And permission in AndroidManifest:

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