• ScrollView中添加ListView


    <p>1.要点一:去除ListView的scrollBar,添加ScrollView的scrollBar:</p>  
    <ScrollView android:layout_width="fill_parent"
                android:layout_height="wrap_content" 
                android:layout_weight="1" 
                android:scrollbars="vertical">
           <LinearLayout android:orientation="vertical" 
                         android:layout_width="fill_parent" 
                         android:layout_height="wrap_content">
                <LinearLayout android:layout_width="fill_parent"
                              android:layout_height="wrap_content"
                              android:orientation="horizontal" 
                              android:paddingLeft="5dp" android:paddingRight="5dp" 
                              android:paddingTop="6dp" android:paddingBottom="6dp"                           
    
    android:background="@color/LightSteelBlue1">
                       
                     <TextView android:id="@+id/text" android:text="列表如下:" 
                               android:layout_width="wrap_content"  android:layout_height="wrap_content"                
    
                android:textColor="@color/White" android:layout_marginLeft="10dp"                                       
    
                android:gravity="center_horizontal" 
                               android:paddingTop="5dp" android:paddingBottom="5dp" android:clickable="true"/>
               </LinearLayout>
               <ListView android:id="@+id/list_alarm" android:layout_width="fill_parent" 
                         android:layout_height="wrap_content" android:layout_weight="1" 
                         android:cacheColorHint="@color/LightCyan2" android:scrollbars="none"/>  
          </LinearLayout>
    </ScrollView>

     2.要点二:(设置ListView的高度,否则只能显示1-2行)

     在setAdapter之后,在设置ListView的高度(不是wrap_content),其高度 = 每行高度 * 行数 + 行间距 * (行数 - 1),用ViewGroup.LayoutParams 设置ListView 的高度

    private void setAdapter(){
            ArrayAdapter<String> adapter = new ArrayAdapter<String>
    
    (MainActivity.this,android.R.layout.simple_list_item_1,listSource);
            mListView.setAdapter(adapter);
            setLvHeight();
        }
        
        private void setLvHeight(){
            ListAdapter adapter = mListView.getAdapter();
            if(adapter == null){
                ShowLog.d(TAG, "no data in ListView");
                return;
            }
            int totalHeight = 0;
            for(int i = 0;i < adapter.getCount(); i++){
                View itemView = adapter.getView(i, null, mListView);
                itemView.measure(0, 0);
                totalHeight += itemView.getMeasuredHeight();
            }
            ViewGroup.LayoutParams layoutParams = mListView.getLayoutParams();
            layoutParams.height = totalHeight + (mListView.getDividerHeight() * (adapter.getCount() - 1));//总行高+每行的间距
            mListView_Alarm.setLayoutParams(layoutParams);
        }
