java - UnsupportedOperationException 打开相机时出错 android

Question

我正在做一个Android应用程序，需要打开相机并在屏幕上显示图片并获取该图片的绝对路径。

但是当我点击相机时，我总是收到“UnsupportedOperationException: Unknown URI: content://media/external/images/media” 错误。

我的代码:

        ContentValues values = new ContentValues();
        values.put(MediaStore.Images.Media.TITLE, "ircms");
        imgUri = getContentResolver().insert(
                MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values); // Here getting error
        Intent intentPicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        intentPicture.putExtra(MediaStore.EXTRA_OUTPUT, imgUri);
        startActivityForResult(intentPicture, 1);

onActivityResult:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
        switch (requestCode) {
        case 1:
            try {
                String photoPath = getRealPathFromURI(this, imgUri);
                o2.inSampleSize = 8;
                Bitmap bitmap = BitmapFactory.decodeFile(photoPath, o2);
                }
       }
}

请帮忙...

试试这个

你需要什么 在Manafiest.xml中

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

在您的 Activity 中

private static final int TAKE_PHOTO_CODE = 1;

private void takePhoto(){
  final Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
  intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(getTempFile(this)) ); 
  startActivityForResult(intent, TAKE_PHOTO_CODE);
}

private File getTempFile(Context context){
  //it will return /sdcard/image.tmp
  final File path = new File( Environment.getExternalStorageDirectory(), context.getPackageName() );
  if(!path.exists()){
    path.mkdir();
  }
  return new File(path, "image.tmp");
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  if (resultCode == RESULT_OK) {
    switch(requestCode){
      case TAKE_PHOTO_CODE:
        final File file = getTempFile(this);
        try {
          Bitmap captureBmp = Media.getBitmap(getContentResolver(), Uri.fromFile(file) );
          // do whatever you want with the bitmap (Resize, Rename, Add To Gallery, etc)
        } catch (FileNotFoundException e) {
          e.printStackTrace();
        } catch (IOException e) {
          e.printStackTrace();
        }
      break;
    }
  }
}
