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); }
