ScrollView中添加ListView

1.要点一：去除ListView的scrollBar,添加ScrollView的scrollBar:

<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);}
