在Android中使用java代码创建Android布局

Question

如何在此图像中添加一个TextView和图像。我想在imageView下添加一个TextView。

public View getView(int position, View convertView, ViewGroup parent) { 
    ImageView imageView; 

    if (convertView == null) { 
     imageView = new ImageView(mContext); 
     imageView.setLayoutParams(new GridView.LayoutParams(400, 400)); 
     imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); 
     imageView.setPadding(8, 8, 8, 8); 
     } else { 
     imageView = (ImageView) convertView; 
    } 

    imageView.setImageResource(mThumbIds[position]); 

    return imageView; 
    } 

Answer 1

您应该使用XML布局编辑器创建网格的行和使用吹气以检索查看Java的对象。以编程方式，像

LinearLayout parent = new LinearLayout(context); 

parent.setLayoutParams(new GridView.LayoutParams(400, 400)); 
parent.setOrientation(LinearLayout.VERTICAL); 

TextView textView = new TextView(context); 
textView.setId(1) 
ImageView imageView = new ImageView(mContext); 
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); 
imageView.setPadding(8, 8, 8, 8); 
imageView.setId(0); 

parent.addView(imageView); 
parent.addView(textView); 

应该这样做。

parent是什么your getView将返回。当然，你必须将演员从ImageView更改为LinearLayout。您可以使用findViewById用0和1，分别检索ImageView和TextView，或getChildAt(0)和getChildAt(1)做

Answer 2

 LinearLayout LL = new LinearLayout(this); 
    LL.setOrientation(LinearLayout.VERTICAL); 

    LayoutParams LLParams = new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT); 

    LL.setLayoutParams(LLParams); 

      ImageView imageView = new ImageView(mContext); 

      //....your imageview code....... 


      TextView textView = new TextView(mContext); 

      //....your textview code....... 


    LL.addView(imageview); 
    LL.addView(textview);
