我的相机应用程序无法正常工作。我尝试了一些现有的教程示例。但他们清楚地给出了编写Android相机应用的代码。我使用了该代码，并且总是得到以下图像错误。

mycode的：

public class MainActivity extends Activity {
    private static int  PICK_FROM_CAMERA =1;
    ImageView iv;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        iv=(ImageView)findViewById(R.id.imageView);

    Button button=(Button)findViewById(R.id.button1);

    button.setOnClickListener(new OnClickListener(){
        @Override
        public void onClick(View view)
        {
             Intent intent = new Intent();
             intent.putExtra("aspectX", 730);
             intent.putExtra("aspectY", 1115);
             intent.putExtra("outputX", 730);
             intent.putExtra("outputY", 1115);
             intent.setAction("android.media.action.IMAGE_CAPTURE");
        startActivityForResult(intent, PICK_FROM_CAMERA);       
    }
         public void onActivityResult(int requestCode, int resultCode, Intent data) 
            {


            // switch(PICK_FROM_CAMERA)
               // {
             //   case PICK_FROM_CAMERA : if (resultCode == RESULT_OK)
              //  { 

             if(requestCode==PICK_FROM_CAMERA&&resultCode==RESULT_OK){
                    ContentValues values = new ContentValues(); 
                    values.put(Images.Media.TITLE, "title");
                    values.put(Images.Media.BUCKET_ID, "test");
                    values.put(Images.Media.DESCRIPTION, "test Image taken");
                    values.put(Images.Media.MIME_TYPE, "image/jpeg");
                    Uri uri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI, values);
                    Bitmap photo = (Bitmap) data.getExtras().get("data");

                    //((ImageView)findViewById(R.id.selectedimage)).setImageBitmap(photo);

                    Bitmap theImage=(Bitmap)data.getExtras().get("data");
                    iv.setImageBitmap(theImage);
                    OutputStream outstream;
                    try {
                        outstream = getContentResolver().openOutputStream(uri);
                        photo.compress(Bitmap.CompressFormat.JPEG,100, outstream);
                        outstream.close();
                } catch (FileNotFoundException e) {}
                catch (IOException e){}
            }
           // break;
                }


    });
    }

更改setAction如下;松开“”

   Intent intent = new Intent();
     intent.putExtra("aspectX", 730);
     intent.putExtra("aspectY", 1115);
     intent.putExtra("outputX", 730);
     intent.putExtra("outputY", 1115);
     intent.setAction(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, PICK_FROM_CAMERA);

清单文件中需要相机权限。你有没有在清单文件中获得许可， 在Android清单文件

中添加此代码 
<uses-permission android:name="android.permission.CAMERA" ></uses-permission>

答案 2 :(得分：0)

尝试在你的意图（）中传递这个。

Intent intent =  new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);

并把它放在你的清单中

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

    <uses-feature android:name="android.hardware.camera" />
    <uses-feature android:name="android.hardware.camera.autofocus" />
