런타임 중에 뷰에서 이미지를 업데이트하거나 변경하십시오.

Question

OnClick 이벤트에서 UI를 업데이트하는 데 약간의 문제가 있습니다.

내가 할 때 :

case R.id.radStripMiningCoal : 
    {  
     LinearLayout testLayout = (LinearLayout)findViewById(R.id.layouttest); 
     LinearLayout layout3 = (LinearLayout)findViewById(R.id.layout2); 
     LinearLayout layout4 = (LinearLayout)findViewById(R.id.layout3); 
     LinearLayout layout = (LinearLayout)findViewById(R.id.recomended); 
     LinearLayout layout2 = (LinearLayout)findViewById(R.id.basic); 


     int origWidth = getWindowManager().getDefaultDisplay().getWidth(); 


     LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(origWidth,LayoutParams.WRAP_CONTENT); 
     layout2.setLayoutParams(params); 
     layout.setLayoutParams(params); 
     testLayout.setLayoutParams(params); 
     layout3.setLayoutParams(params); 
     layout4.setLayoutParams(params); 

     stripminingcoal.setVisibility(View.VISIBLE); 
     VSLists.setVisibility(View.GONE); 
     Next.setVisibility(View.GONE); 

      AnimationDrawable animation = new AnimationDrawable(); 

      animation.addFrame(getResources().getDrawable(R.drawable.multispd1), 5000); 
      animation.addFrame(getResources().getDrawable(R.drawable.img1), 5000); 
      animation.addFrame(getResources().getDrawable(R.drawable.shocktubecluster1), 5000); 
      animation.setOneShot(false); 

      ImageView imageAnim = (ImageView) findViewById(R.id.imgBasicIS);   
      imageAnim.setBackgroundDrawable(animation);    
      animation.start(); 

      AnimationDrawable animation2 = new AnimationDrawable(); 
      animation2.addFrame(getResources().getDrawable(R.drawable.unidelaysp), 5000); 
      animation2.addFrame(getResources().getDrawable(R.drawable.trunkline), 5000);     
      animation2.setOneShot(false); 

      ImageView imageAnim2 = (ImageView) findViewById(R.id.imgRecomendedIS);   
      imageAnim2.setBackgroundDrawable(animation2);    
      animation2.start(); 

      AnimationDrawable animation3 = new AnimationDrawable(); 

      animation3.addFrame(getResources().getDrawable(R.drawable.leadin2), 5000); 
      animation3.addFrame(getResources().getDrawable(R.drawable.tubestarter),5000); 
      animation3.setOneShot(false); 
      ImageView imageAnim3 = (ImageView) findViewById(R.id.imgRecomendedBSS);    
      imageAnim3.setBackgroundDrawable(animation3);   
      animation3.start(); 

      txtBasicIS.setText("Shock Tube Multi SPD/Detonating Cord/Cluster"); 
      txtRecomendedIS.setText("Shock Tube Uni-Delay SP/Trunkline"); 
      txtRecomendedBSS.setText("Lead-In Line/Electric Shock Tube Starter"); 

모든 업데이트와 잘 표시됩니다. 그러나의 내가 "사건"의 다른에서 동일한 코드를하는 것처럼 곧 새로운 이미지로 이미지를 업데이트하지 않습니다 : I가 없거나 잘못을하고있는 중이 야 무엇

case R.id.radNarrowReefGold: 
    { 
     LinearLayout testLayout = (LinearLayout)findViewById(R.id.layouttest); 
     LinearLayout layout3 = (LinearLayout)findViewById(R.id.layout2); 
     LinearLayout layout4 = (LinearLayout)findViewById(R.id.layout3); 
     LinearLayout layout = (LinearLayout)findViewById(R.id.recomended); 
     LinearLayout layout2 = (LinearLayout)findViewById(R.id.basic); 


     int origWidth = getWindowManager().getDefaultDisplay().getWidth(); 


     LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(origWidth,LayoutParams.WRAP_CONTENT); 
     layout2.setLayoutParams(params); 
     layout.setLayoutParams(params); 
     testLayout.setLayoutParams(params); 
     layout3.setLayoutParams(params); 
     layout4.setLayoutParams(params); 

     stripminingcoal.setVisibility(View.VISIBLE); 
     VSLists.setVisibility(View.GONE); 
     Next.setVisibility(View.GONE); 

      AnimationDrawable animation = new AnimationDrawable(); 

      animation.addFrame(getResources().getDrawable(R.drawable.udlp3), 5000); 
      animation.addFrame(getResources().getDrawable(R.drawable.udlp6), 5000); 
      animation.addFrame(getResources().getDrawable(R.drawable.trunkline), 5000); 
      animation.setOneShot(false); 

      ImageView imageAnim = (ImageView) findViewById(R.id.imgBasicIS);   
      imageAnim.setBackgroundDrawable(animation);    
      animation.start(); 

      AnimationDrawable animation2 = new AnimationDrawable(); 
      animation2.addFrame(getResources().getDrawable(R.drawable.udlp3vivid), 5000); 
      animation2.addFrame(getResources().getDrawable(R.drawable.udlp6vivid), 5000); 
      animation2.addFrame(getResources().getDrawable(R.drawable.trunkline), 5000);     
      animation2.setOneShot(false); 

      ImageView imageAnim2 = (ImageView) findViewById(R.id.imgRecomendedIS);   
      imageAnim2.setBackgroundDrawable(animation2);    
      animation2.start(); 

      AnimationDrawable animation3 = new AnimationDrawable(); 

      animation3.addFrame(getResources().getDrawable(R.drawable.leadin2), 5000); 
      animation3.addFrame(getResources().getDrawable(R.drawable.tubestarter),5000); 
      animation3.setOneShot(false); 
      ImageView imageAnim3 = (ImageView) findViewById(R.id.imgRecomendedBSS);    
      imageAnim3.setBackgroundDrawable(animation3);   
      animation3.start(); 

      txtBasicIS.setText("Uni-Delay LP (3)/Uni-Delay LP (6)/Trunkline"); 
      txtRecomendedIS.setText("Shock Tube Uni-Delay SP/Trunkline"); 
      txtRecomendedBSS.setText("Lead-In Line/Electric Shock Tube Starter"); 
    } 

를?

textViews도 변경되지 않습니다.

미리 감사드립니다. 패트릭

Answer 1

누락 된 "휴식;" 귀하의 스위치 케이스 구조에있는 진술.

내가 직접 작성한 다음 작은 스 니펫을 사용하여이를 테스트 할 수 있습니다. 휴식 시간을 제거한다면; 성명서를 통해 MESSI에 글을 올릴 수는 없지만 RONALDO 만 보여줍니다. 즉, 논리가 깨졌습니다.

"휴식;" MESSI와 RONALDO 사이를 전환 할 수 있습니다.

시도가 img.SetImageResource을 추가하기 (0); 이전 줄 앞에. 그것은 당신에게 명성을 쌓았습니다
