將拍攝的照片從ImageView存儲到手機存儲器

拍攝照片後，我將照片存儲到ImageView中，因此，如果任何人有任何想法或建議如何在ImageView上顯示圖片後將圖片存儲到沒有用戶的手機舞臺中互動在此先感謝將拍攝的照片從ImageView存儲到手機存儲器

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); 
    } 

} 

}

嘗試：

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

並保存：

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) { 
    }

和權限在AndroidManifest：

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