조각 내 ViewPager가 표시되지 않음 ImageView가 표시됩니다.

Question

을 사용하여 carousel view을 사용하려고합니다. 이는 Fragment입니다.
Fragment도 MainActivity에있는 다른 ViewPager에 의해 보여진다.

단편의 ViewPager에는 ImageView이 표시되지 않습니다.
나는 ViewPager의 배경을 변경하고 각각 ImageView의 배경을 변경했기 때문에, 배경은 ImageView 님의 배경이 표시되지 않았 음을 고려하면 ViewPager은 괜찮다고 생각합니다.

도와주세요.

BaseActivity는 AppCompatActivity 익스텐트있는 편리한입니다.

</LinearLayout> 

Answer 1

은 다음과 같이이다 :

 ViewPager viewPager = (ViewPager) findViewById(R.id.container); 
     viewPager.setAdapter(jobTitlePagerAdapter); 
     TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs); 
     tabLayout.setupWithViewPager(viewPager); 

희망 당신은 의심의 여지가이 help..If 다음 PLS 나 한테 물어.

Answer 2

장치의 비트 맵 제한에 대한 예외가 있습니다. 이 예외는 앱을 중지하지 않지만 기기 제한으로 인해 배경 드로어 블을 볼 수 없습니다. 모든 기기에는 자체 제한이 있습니다. drawables가 너무 작다고 생각하지 마십시오. 화면에 많은 이미지가 있으면 그 한계에 도달하게됩니다.

On This Post "캔버스 : 너무 큰 (216090000 바이트) 비트 맵을 그리는 중"을 방지하는 방법 예외가 설명됩니다.

나는 이것이 당신의 문제라고 말하지 않고 있지만 그럴 수 있습니다.
