【问题描述】：

拍完照片后，我将图片存储到 ImageView 中，因此，如果有人对如何在 ImageView 上显示的图片在无需用户交互的情况下将其存储到手机阶段有任何想法或建议在此先感谢

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);
    }

}

}

【解决方案1】：

试试：

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

然后保存：

 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) {
   }

AndroidManifest 中的权限：

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