将拍摄的照片从ImageView存储到手机存储器

拍摄照片后，我将照片存储到ImageView中，因此，如果任何人有任何想法或建议如何在ImageView上显示图片后将图片存储到没有用户的手机舞台中互动在此先感谢将拍摄的照片从ImageView存储到手机存储器

enter image description here

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); 
    } 

} 

}

尝试：

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

并保存：

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) { 
    }

和权限在AndroidManifest：

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