Question

package com.example.five;

 

import java.util.Random;

 

import android.content.Context;

import android.os.Bundle;

import android.support.v4.app.Fragment;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.ImageView;

 

import com.example.five.R;

 

 

 

public class Tab01 extends Fragment {

 

 

 

Context mContext;

 

public Tab01(Context context) {

mContext = context;

}

public Tab01() {

 

 

}

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

View view = inflater.inflate(R.layout.activity_tab01, null);

return view;

}

@Override

public void onCreate(Bundle savedInstanceState){

 super.onCreate(savedInstanceState);

int[] images ={R.drawable.a1, R.drawable.a2, R.drawable.a3};

 

// Get the ImageView

 

setContentView(R.layout.activity_tab01);

ImageView mImageView = (ImageView)getActivity().findViewById(R.id.myImageView);

 

// Get a random between 0 and images.length-1

int imageId = (int)(Math.random() * images.length);

 

// Set the image

mImageView.setBackgroundResource(images[imageId]);

 

 

}

 

 

 

}

 

 

굵게 칠해놓은 이 쪽이 자꾸 불이 들어오는데요 

 

뭐가 문제인건가요 ?ㅠㅠ 예전에 레이팅바 넣을때는 저렇게 해서 됏는데 지금은 onCreatView 안에 넣어서 view.findViewById 해도 안되네여 ㅠㅠ 도와주소서 ㅠㅠ

Answer 1

setContentView(R.layout.activity_tab01);

 

대신에

 

View view = inflater.inflate(R.layout.dialer, null);

 

를 해보시겠어요?

그래도 불 들어오네요  inflater,dialer 부분요

inflater 임포트 하고 dialer activity_tab01 로 바꾸면 inflate 가 불들어오네요 ㅠ.ㅠ

Answer 2

 

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

View view = inflater.inflate(R.layout.activity_tab01, null);

return view;

}

@Override

public void onCreate(Bundle savedInstanceState){

 super.onCreate(savedInstanceState);

int[] images ={R.drawable.a1, R.drawable.a2, R.drawable.a3};

 

// Get the ImageView

 

setContentView(R.layout.activity_tab01);

ImageView mImageView = (ImageView)getActivity().findViewById(R.id.myImageView);

 

// Get a random between 0 and images.length-1

int imageId = (int)(Math.random() * images.length);

 

// Set the image

mImageView.setBackgroundResource(images[imageId]);

 

 

}

 

 

 

 

이부분을 아래와같이 바꾸세요

oncreate 함수는 다 지우시고

oncreateview 함수만 남겨두세요

 

 

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

 

 

View view = inflater.inflate(R.layout.activity_tab01, null);

 

ImageView mImageView = (ImageView)view .findViewById(R.id.myImageView);

 

int[] images ={R.drawable.a1, R.drawable.a2, R.drawable.a3};

// Get a random between 0 and images.length-1

int imageId = (int)(Math.random() * images.length);

// Set the image

mImageView.setBackgroundResource(images[imageId]);

 

 

return view;

}
