嗨大家好, 我用android開發。我是android開發新手。我將數據綁定到gridview控件。我做的。我在我的GridView中有4列,然後我只添加第五列作爲複選框。我使用了一個coidng,即每個列都有複選框。我只需要把最後一列。我的佈局是:如何添加複選框在android中的gridview中

<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" 
android:paddingBottom="@dimen/activity_vertical_margin" 
android:paddingLeft="@dimen/activity_horizontal_margin" 
android:paddingRight="@dimen/activity_horizontal_margin" 
android:paddingTop="@dimen/activity_vertical_margin" 
tools:context=".MainActivity" > 

<GridView 
    android:id="@+id/gridView1" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:layout_below="@+id/spinner2" 
    android:layout_marginTop="80dp" 
    android:layout_toRightOf="@+id/textView2" 
    android:numColumns="4" > 
</GridView> 

我的編碼是:

grid = (GridView) findViewById(R.id.gridView1);  
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout .simple_ list _item_multiple_choice, letters); 
    grid.setAdapter(adapter);

使用BaseAdapter類在GridView控件與添加數據自定義佈局有複選框 – Meenal

亞,但有些時候鏈接是exipred,所以我們必須這樣發佈 –

設置網格選擇模式到多個。

grid.setChoiceMode(2);

這可能會幫助你...

設置的數列5 GridView和使用position檢查當前列索引...

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, 
      android.R.layout.simple_list_item_multiple_choice, letters) { 
     @Override 
     public View getView(int position, View convertView, ViewGroup parent) { 
      if ((position + 1) % 5 != 0) { 
       return super.getView(position, convertView, parent); 
      } else { 
       if (convertView == null || !(convertView instanceof CheckBox)) { 
        CheckBox checkBox = new CheckBox(getContext()); 
        convertView = checkBox; 
       } 
       ((CheckBox)convertView).setText(getItem(position)); 
       return convertView; 
      } 
     } 
    };
