电话内置摄像头的意图有图片。

Call inbuilt camera intent to have picture.

public class demo extends Activity {

Button ButtonClick;
int CAMERA_PIC_REQUEST = 1337; 


@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 == 1337)
    {
    //  data.getExtras()
        Bitmap thumbnail = (Bitmap) data.getExtras().get("data");

          Now you have received the bitmap..you can pass that bitmap to other activity
          and play with it in this activity or pass this bitmap to other activity
          and then upload it to server.
    }
    else 
    {
        Toast.makeText(demo.this, "Picture NOt taken", Toast.LENGTH_LONG);
    }
    super.onActivityResult(requestCode, resultCode, data);
}
}
