在此先感谢

推荐答案

试试这个

 Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(i , 0);          

和调用这个

@Override
protected void onActivityResult(int requestCode, int resultCode,
        Intent resultData) {
    super.onActivityResult(requestCode, resultCode, resultData);

        if (resultData != null) {

        String[] projection = { MediaStore.Images.Media.DATA };
                Cursor cursor = managedQuery(
                        MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                        projection, null, null, null);
                int column_index_data = cursor
                        .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
                cursor.moveToLast();

                String imagePath = cursor.getString(column_index_data);
                Bitmap bitmapImage = BitmapFactory.decodeFile(imagePath );
                imageView.setImageBitmap(bitmapImage );

            }

和使用你想要的prrmission

and use the prrmission what you want

 <uses-permission android:name="android.permission.CAMERA" /> 
    <permission android:name="android.permission.FLASHLIGHT" />
    <uses-feature android:name="android.hardware.camera"/>
