java - textview不显示文本

Question

我创建了包含问题文本和适合提问的输入字段的表单。我的表单中有微调器、编辑文本和复选框。所有这些都是使用 Activity 动态创建的。创建的布局中的问题是输入字段显示正确，但 TextView 未显示。

   private void  showIssueForm(){
    for (int i=0;i<claimQuestionList.size();i++){
        ClaimQuestion claimQuestion=claimQuestionList.get(i);
        LinearLayout linearLayout=ClaimUtils.createLayoutForClaimQuestion(claimQuestion,this);
        /*claimQuestionsLinearLayout.addView(linearLayout);*/
        claimQuestionsLinearLayout.addView(linearLayout,i);
    }

}   


 private static TextView createTextView(ClaimQuestion claimQuestion,Context context){                                               
 TextView textView=new TextView(context);                                                                                       
 LinearLayout.LayoutParams textViewLayoutParams=new LinearLayout.LayoutParams(300,80,1);                                        
 textView.setText("hi m printing the text what are you looking for");//claimQuestion.getOrder()+". "+claimQuestion.getLabel()); 
 textView.setLayoutParams(textViewLayoutParams);                                                                                
 //textView.setMinLines(1);                                                                                                     
// textView.setSingleLine(false);                                                                                               
 textView.setTextSize(R.dimen.system12);                                                                                        
 textView.setVisibility(View.VISIBLE);                                                                                          
 textView.setTextColor(context.getResources().getColor(R.color.light_white_));                                                  
 return textView;                                                                                                               

}

下面给出了我添加表单元素的线性布局

  public static LinearLayout createLayoutForClaimQuestion(ClaimQuestion claimQuestion,Context context){   
 LinearLayout linearLayout=new LinearLayout(context);                                                
 LinearLayout.LayoutParams linearLayoutParams=new LinearLayout.LayoutParams(500,200);                
 linearLayout.setLayoutParams(linearLayoutParams);                                                   
 linearLayout.setOrientation(LinearLayout.VERTICAL);                                                 
 TextView questionLabel=createTextView(claimQuestion,context);                                       
 linearLayout.addView(questionLabel,0);                                                              
 if (claimQuestion.getQuestionType()==ClaimQuestion.QuestionTypeEnum.CQ_TEXT){                       
     EditText editText=createEditText(claimQuestion,context);                                        
     linearLayout.addView(editText,1);                                                               
 }else if(claimQuestion.getQuestionType()==ClaimQuestion.QuestionTypeEnum.CQ_CHECKBOX){              
     CheckBox checkBox=createCheckBox(claimQuestion,context);                                        
     linearLayout.addView(checkBox,1);                                                               
 }else if(claimQuestion.getQuestionType()==ClaimQuestion.QuestionTypeEnum.CQ_SELECT){                
     Spinner spinner=createSpinner(claimQuestion,context);                                           
     linearLayout.addView(spinner,1);                                                                
 }                                                                                                   
 return linearLayout;                                                                                

}

父布局的xml布局文件是

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.maximus.mycar.VehicleSelectActivity"
android:background="@drawable/bluebg_320_568">
<include layout="@layout/header"
    android:id="@+id/top_header_layout_ici"
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    android:layout_marginTop="10dp"/>
<ScrollView
    android:id="@+id/claim_questions_scroll_view"
    android:layout_below="@id/top_header_layout_ici"
    android:layout_height="fill_parent"
    android:layout_width="fill_parent"
    android:layout_marginBottom="20dp"
    >
    <LinearLayout
        android:id="@+id/claim_questions_linear_layout"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

    </LinearLayout>
</ScrollView>

我通过设置固定值更改了字体大小，然后它工作正常。

textView.setTextSize(12);
