如何设置4个图像为线性布局根据android

Question

中的设备线性布局我有4个图像在linearlayout内以编程方式创建，我想在第四个图像上设置textview如何设置??如果你有一块代码请分享跟我？？

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, 300, 1.0f); 

public void path(ArrayList<Integer> integerImg) { 
    // int width=mContext.getWgetWindowManager().getDefaultDispaly.getWidth(); 
    ImageView images; 
    for (int i = 0; i < integerImg.size(); i++) { 
     if (i < 4) { 
      images = new ImageView(mContext); 
      params.setMargins(10, 0, 0, 0); 
      images.setLayoutParams(params); 
      images.setScaleType(ImageView.ScaleType.FIT_XY); 
      images.setBackgroundResource(R.drawable.salon_profile_back); 
      images.setImageResource(integerImg.get(i)); 
      linearImgGrid.addView(images); 
     } 

Answer 1

试试这个

TextView tv= new TextView(this); 
      tv.setText("hallo hallo"); 
      tv.setId(5); 
      tv.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT)); 
    //add the 4th linear layout 
      ((LinearLayout) linearLayout).addView(tv);

可以在LinearLayout使用下面的代码以供参考

<LinearLayout 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" 
     android:orientation="vertical" > 

     <LinearLayout 
      android:layout_width="match_parent" 
      android:layout_height="96dp" 
      android:layout_marginTop="70dp" 
      android:weightSum="3" 

      android:orientation="horizontal" > 


      <LinearLayout 
      android:layout_width="wrap_content"

Answer 3

而不是添加ImageView，你可以创建一个RelativeLayout把一个ImageView内和TextView并添加RelativeLayout到LinearLayout，因为这样：

RelativeLayout.LayoutParams layoutParamsImage = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, 
      RelativeLayout.LayoutParams.MATCH_PARENT); 
    RelativeLayout.LayoutParams layoutParamsText = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, 
      RelativeLayout.LayoutParams.WRAP_CONTENT); 
    layoutParamsText.addRule(RelativeLayout.CENTER_IN_PARENT); 


    for (int i = 0; i < integerImg.size(); i++) { 
     if (i < 4) { 

      RelativeLayout relativeLayout = new RelativeLayout(mContext); 
      relativeLayout.setLayoutParams(params); 




      ImageView images = new ImageView(mContext); 
      params.setMargins(10, 0, 0, 0); 
      images.setLayoutParams(layoutParamsImage); 
      images.setScaleType(ImageView.ScaleType.FIT_XY); 
      images.setBackgroundResource(R.drawable.salon_profile_back); 
      images.setImageResource(integerImg.get(i)); 
      relativeLayout.addView(images); 

      TextView textView = new TextView(mContext); 
      textView.setLayoutParams(layoutParamsImage); 
      textView.setText("My Text"); 
      relativeLayout.addView(textView); 

      linearImgGrid.addView(relativeLayout); 
     } 
    }
