ListView 表格動態設置控件寬度

在用ListView作表格時我想你們都遇到和我同樣的問題如圖

解決這個問題大部都會想到動態設置控件寬度，繼承 SimpleAdapter 重寫 public View getView(int position,View convertView,ViewGroup parent)方法，代碼以下：

[java] view plain copy print ?

1. package com.TableTest; 
2. import java.util.List; 
3. import java.util.Map; 
4. import android.content.Context; 
5. import android.view.View; 
6. import android.view.ViewGroup; 
7. import android.widget.LinearLayout; 
8. import android.widget.SimpleAdapter; 
9. public class TableAdapter extends SimpleAdapter { 
10.     private int screenWidth;//屏幕寬度 
11.     public int getScreenWidth() { 
12.         return screenWidth; 
13.     } 
14.     public void setScreenWidth(int screenWidth) { 
15.         this.screenWidth = screenWidth; 
16.     } 
17.     public TableAdapter(Context context, List<? extends Map<String, ?>> data,int resource, String[] from, int[] to) { 
18.         super(context, data, resource, from, to); 
19.     } 
20.     public View getView(int position,View convertView,ViewGroup parent){ 
21.          
22.         int itemWidth = (screenWidth - 10) / 3; 
23.         View view = super.getView(position,convertView,parent); 
24.          
25.         View table_item_item0 = view.findViewById(R.id.table_item_item0); 
26.         View table_item_item1 = view.findViewById(R.id.table_item_item1); 
27.         View table_item_item2 = view.findViewById(R.id.table_item_item2); 
28.          
29.         LinearLayout.LayoutParams linearParams0 = (LinearLayout.LayoutParams)table_item_item0.getLayoutParams(); 
30.         linearParams0.width = itemWidth; 
31.         table_item_item0.setLayoutParams(linearParams0); 
32.          
33.         LinearLayout.LayoutParams linearParams1 = (LinearLayout.LayoutParams)table_item_item1.getLayoutParams(); 
34.         linearParams1.width = itemWidth; 
35.         table_item_item1.setLayoutParams(linearParams1); 
36.          
37.         LinearLayout.LayoutParams linearParams2 = (LinearLayout.LayoutParams)table_item_item2.getLayoutParams(); 
38.         linearParams2.width = itemWidth; 
39.         table_item_item2.setLayoutParams(linearParams2); 
40.          
41.         return  view; 
42.     } 
43. } 

package com.TableTest;
import java.util.List;
import java.util.Map;
import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.LinearLayout;
import android.widget.SimpleAdapter;
public class TableAdapter extends SimpleAdapter {
private int screenWidth;//屏幕寬度
public int getScreenWidth() {
return screenWidth;
}
public void setScreenWidth(int screenWidth) {
this.screenWidth = screenWidth;
}
public TableAdapter(Context context, List<? extends Map<String, ?>> data,int resource, String[] from, int[] to) {
super(context, data, resource, from, to);
}
public View getView(int position,View convertView,ViewGroup parent){
int itemWidth = (screenWidth - 10) / 3;
View view = super.getView(position,convertView,parent);
View table_item_item0 = view.findViewById(R.id.table_item_item0);
View table_item_item1 = view.findViewById(R.id.table_item_item1);
View table_item_item2 = view.findViewById(R.id.table_item_item2);
LinearLayout.LayoutParams linearParams0 = (LinearLayout.LayoutParams)table_item_item0.getLayoutParams();
linearParams0.width = itemWidth;
table_item_item0.setLayoutParams(linearParams0);
LinearLayout.LayoutParams linearParams1 = (LinearLayout.LayoutParams)table_item_item1.getLayoutParams();
linearParams1.width = itemWidth;
table_item_item1.setLayoutParams(linearParams1);
LinearLayout.LayoutParams linearParams2 = (LinearLayout.LayoutParams)table_item_item2.getLayoutParams();
linearParams2.width = itemWidth;
table_item_item2.setLayoutParams(linearParams2);
return  view;
}
}

效果如圖

解決上列問題還有一個更簡單的方法 就是把 表格裏的控件設置一個超長值如 android:layout_width="1000px"

代碼以下

[xhtml] view plain copy print ?

1. <?xml version="1.0" encoding="utf-8"?> 
2. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
3.     android:layout_width="fill_parent" 
4.     android:layout_height="wrap_content" 
5.     android:orientation="horizontal"> 
6.     <TextView android:id="@+id/table_item_item0"  
7.     android:layout_width="1000px"  
8.     android:layout_height="wrap_content"  
9.     android:singleLine="true"  
10.     android:textColor="#ff133447" 
11.     android:layout_gravity="center" 
12.     android:gravity="center" 
13.     android:paddingTop="2px" 
14.     android:paddingBottom="2px" 
15.     android:layout_weight="1" /> 
16.     <View android:layout_width="1px"  
17.     android:layout_height="fill_parent" 
18.     android:background="#ff000000" /> 
19.     <TextView android:id="@+id/table_item_item1"  
20.     android:layout_width="1000px"  
21.     android:layout_height="wrap_content"  
22.     android:singleLine="true"  
23.     android:textColor="#ff133447" 
24.     android:layout_gravity="center" 
25.     android:gravity="center" 
26.     android:paddingTop="2px" 
27.     android:paddingBottom="2px" 
28.     android:layout_weight="1" /> 
29.     <View android:layout_width="1px"  
30.     android:layout_height="fill_parent"  
31.     android:background="#ff000000" /> 
32.     <TextView android:id="@+id/table_item_item2"  
33.     android:layout_width="1000px"  
34.     android:layout_height="wrap_content"  
35.     android:singleLine="true"  
36.     android:textColor="#ff133447" 
37.     android:layout_gravity="center" 
38.     android:gravity="center" 
39.     android:paddingTop="2px" 
40.     android:paddingBottom="2px" 
41.     android:layout_weight="1" /> 
42. </LinearLayout>
