我使用下面的code。通过使用意图使用相机。
在意向中的参数我传递 android.provider.MediaStore.ACTION_IMAGE_CAPTURE
。
它是能够打开相机。
但问题是,它意外停止。
现在的问题是,它给空指针异常的 OnActivityResults
。
我已经使用了低于code:
I am using the following code to use camera by using intent.
In the parameter of intent I am passing android.provider.MediaStore.ACTION_IMAGE_CAPTURE
.
It is able to open the camera.
But the problem is that it stops unexpectedly.
The problem is that it gives null pointer exception on OnActivityResults
.
I have used the below code:
public class demo extends Activity {
Button ButtonClick;
int CAMERA_PIC_REQUEST = 2;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ButtonClick =(Button) findViewById(R.id.Camera);
ButtonClick.setOnClickListener(new OnClickListener (){
@Override
public void onClick(View view)
{
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
// request code
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
if( requestCode == CAMERA_PIC_REQUEST)
{
// data.getExtras()
Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
ImageView image =(ImageView) findViewById(R.id.PhotoCaptured);
image.setImageBitmap(thumbnail);
}
else
{
Toast.makeText(demo.this, "Picture NOt taken", Toast.LENGTH_LONG);
}
super.onActivityResult(requestCode, resultCode, data);
}
}
谁能帮我解决这个问题?
Can anyone help me to solve this problem?
尝试请求code 1337。
Try request code 1337.
startActivityForResult(cameraIntent , 1337);
