如何在Android中动态添加多个togglebutton的setOnCheckedChangeListener

Question

我已成功添加动态多个togglebutton在activity。但我坚持处理setOnCheckedChangeListener每个togglebutton。

我创建了演示代码片段。

linearLayout = (LinearLayout) findViewById(R.id.linearLayout); 

     for (int i = 0; i < 6; i++) { 

      el = new LinearLayout(this); 
      el.setOrientation(LinearLayout.HORIZONTAL); 

      LinearLayout.LayoutParams emailLinearParams = new LinearLayout.LayoutParams(
        LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT); 

      el.setLayoutParams(emailLinearParams); 
      el.setPadding(5, 5, 5, 5); 

      LinearLayout.LayoutParams emailTxtParams = new LinearLayout.LayoutParams(
        LayoutParams.WRAP_CONTENT, LayoutParams.MATCH_PARENT, 0.9f); 

      TextView emailTxt = new TextView(this); 
      emailTxt.setText("demo"); 
      emailTxt.setLayoutParams(emailTxtParams); 
      emailTxt.setGravity(Gravity.CENTER_VERTICAL); 

      el.addView(emailTxt); 

      ToggleButton toggleEmailBtn = new ToggleButton(this); 

      LinearLayout.LayoutParams emailToggleBtnParams = new LinearLayout.LayoutParams(
        LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 0.1f); 

      toggleEmailBtn.setLayoutParams(emailToggleBtnParams); 

      el.addView(toggleEmailBtn); 

      linearLayout.addView(el); 

     }

尝试并有很好的答案:)

ToggleButton tglBtn[]; 

在onCreate()

tglBtn = new ToggleButton[6]; 

    for (int i = 0; i < 6; i++) { 

      el = new LinearLayout(this); 
      el.setOrientation(LinearLayout.HORIZONTAL); 

      LinearLayout.LayoutParams emailLinearParams = new LinearLayout.LayoutParams(
        LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT); 

      el.setLayoutParams(emailLinearParams); 
      el.setPadding(5, 5, 5, 5); 

      LinearLayout.LayoutParams emailTxtParams = new LinearLayout.LayoutParams(
        LayoutParams.WRAP_CONTENT, LayoutParams.MATCH_PARENT, 0.9f); 

      TextView emailTxt = new TextView(this); 
      emailTxt.setText("demo"); 
      emailTxt.setLayoutParams(emailTxtParams); 
      emailTxt.setGravity(Gravity.CENTER_VERTICAL); 

      el.addView(emailTxt); 

      tglBtn[i] = new ToggleButton(this); 

      LinearLayout.LayoutParams emailToggleBtnParams = new LinearLayout.LayoutParams(
        LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 0.1f); 

      tglBtn[i].setLayoutParams(emailToggleBtnParams); 

      el.addView(tglBtn[i]); 

      linearLayout.addView(el); 

      tglBtn[i] 
        .setOnCheckedChangeListener(handleOnClick(
          tglBtn[i], i)); 

     } 

使用的方法解决对togglebuttons

CompoundButton.OnCheckedChangeListener handleOnClick(
      final ToggleButton button, final int id) { 
     return new CompoundButton.OnCheckedChangeListener() { 
      @Override 
      public void onCheckedChanged(CompoundButton cbtn, boolean isCheck) { 
        Log.d(TAG, "clicked "+id); 
      } 
     }; 
    }
