请帮我解决Android相机问题

Question

亲爱的世界安卓开发者。

请帮我解决 android camera API 问题。

我想通过 android 相机拍照并将其设置为 ImageButton 的图像。 如果有媒体存储，则将图像保存到特殊路径。

问题如下。

适用于部分安卓设备，如中兴2.2、三星Galaxy 2.3.3、三星平板4.0.3等。

但它不适用于其他一些设备，例如 2.3.4 LG Droid。

我的意思是捕获的图像没有设置为图像按钮。

(2.3.4 LG Droid 的详细设备信息为： 硬件版本：Rev .1.1， 软件版本：ms910zbc， 内部版本号姜饼）

这是我的代码。

String mPhotoPath;
ImageButton mPhotoButton;

mPhotoButton.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        String storageState = Environment.getExternalStorageState();
        if (storageState.equals(Environment.MEDIA_MOUNTED)) {
            File photoFile = new File(mPhotoPath);
            try {
                if (!photoFile.exists()) {
                    photoFile.getParentFile().mkdirs();
                    photoFile.createNewFile(); 
                    photoFile.setWritable(true, false);
                } 
            } catch (IOException e) {

            }

            Uri fileUri = Uri.fromFile(photoFile);
            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
            startActivityForResult(intent, TAKE_PICTURE);
        }else {
            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(intent, TAKE_PICTURE);
        }
    }
});



protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode != RESULT_OK) {
        return;
    }
    switch (requestCode) {
        case TAKE_PICTURE: {
            if (data != null) { //ZTE 2.2 device
                try {
                    Bundle extras = data.getExtras();
                    if (extras != null)
                    {
                        fPhoto = extras.getParcelable("data");
                        mPhotoButton.setImageBitmap(fPhoto);
                    }                       
                } catch (Exception e) {
                    e.printStackTrace();
                }
            } 
            else //Samsung 2.3.3 device
            {
                try {
                     FileInputStream stream = new FileInputStream(new File(mPhotoPath));
                     fPhoto = BitmapFactory.decodeStream(stream);
                     stream.close();
                     mPhotoButton.setImageBitmap(fPhoto);
                }catch (Exception e) {
                     e.printStackTrace();
                }
            }
            break;
       }
    }
}

感谢您的所有帮助。

谢谢。

真诚的。

public class Camera extends Activity 
  {
 private static final int CAMERA_REQUEST = 1888;
 private String selectedImagePath;
 ImageButton mPhotoButton;

@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    mPhotoButton=(Button)findElementById(R.id.imgbtn1);
    mPhotoButton.setOnClickListener(new OnClickListener()
   {
        @Override
        public void onClick(View v) 
        {
            Intent cameraIntent = new Intent(ACTION_IMAGE_CAPTURE);
            startActivityForResult(cameraIntent, CAMERA_REQUEST);
        }
   }
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
    if (resultCode == RESULT_OK) {
        if (requestCode == CAMERA_REQUEST) 
        { 
            Bitmap photo = (Bitmap) data.getExtras().get("data"); 
            ByteArrayOutputStream bytes = new ByteArrayOutputStream();
            photo.compress(Bitmap.CompressFormat.JPEG, 40, bytes);
            Random randomGenerator = new Random();randomGenerator.nextInt();
            String newimagename=randomGenerator.toString()+".jpg";
            File f = new File(Environment.getExternalStorageDirectory()
                                    + File.separator + newimagename);
            try {
                f.createNewFile();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            //write the bytes in file

            try {
                fo = new FileOutputStream(f.getAbsoluteFile());
            } catch (FileNotFoundException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            try {
                fo.write(bytes.toByteArray());
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
                uri=f.getAbsolutePath(); 
                mPhotoButton.setImageResource(uri);
    //this is the url that where you are saved the image
      }



  }
