我有一个线性布局,其中包含三个列表视图和三个按钮。我已经定制了列表视图元素。我只希望如果有人触摸列表视图的元素,则相应的文本视图应作为选取框生效。
主要的线性布局如下-
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:orientation="vertical" >
<ListView
android:id="@+id/list1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginLeft="5dip"
android:layout_marginRight="5dip"
android:layout_marginTop="5dip"
android:layout_weight="1"
android:drawSelectorOnTop="false"
android:textSize="16dip" />
<Button
android:id="@+id/more_button1"
android:layout_width="130dip"
android:layout_height="wrap_content"
android:layout_marginLeft="5dip"
android:layout_marginRight="5dip"
android:layout_marginTop="5dip"
android:text="More" >
</Button>
<ListView
android:id="@+id/list2"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginLeft="5dip"
android:layout_marginRight="5dip"
android:layout_marginTop="5dip"
android:layout_weight="1"
android:drawSelectorOnTop="false"
android:textSize="16dip" />
<Button
android:id="@+id/more_button2"
android:layout_width="130dip"
android:layout_height="wrap_content"
android:layout_marginLeft="5dip"
android:layout_marginRight="5dip"
android:layout_marginTop="5dip"
android:text="More" >
</Button>
<ListView
android:id="@+id/list3"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginLeft="5dip"
android:layout_marginRight="5dip"
android:layout_marginTop="5dip"
android:layout_weight="1"
android:drawSelectorOnTop="false"
android:textSize="16dip" />
<Button
android:id="@+id/more_button3"
android:layout_width="130dip"
android:layout_height="wrap_content"
android:layout_marginLeft="5dip"
android:layout_marginRight="5dip"
android:layout_marginTop="5dip"
android:text="More" >
</Button>
</LinearLayout>
自定义列表项如下(list_item_1,list_item_2,list_item_3)-
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:ellipsize="marquee"
android:focusableInTouchMode="true"
android:freezesText="true"
android:lines="1"
android:marqueeRepeatLimit="marquee_forever"
android:padding="10dp"
android:scrollHorizontally="true"
android:scrollbarAlwaysDrawVerticalTrack="false"
android:singleLine="true"
android:textSize="20sp" >
</TextView>
活动如下-
public class MarqueeActivity extends Activity {
ListView lv1 = null;
ListView lv2 = null;
ListView lv3 = null;
String s1[] = {"Hello This is a long Text which will help in tsting", "How", "Are", "You"};
String s2[] = {"I", "Am", "Fine"};
String s3[] = {"Welcome", "In", "New", "World"};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
lv1 = (ListView) findViewById(R.id.list1);
lv2 = (ListView) findViewById(R.id.list2);
lv3 = (ListView) findViewById(R.id.list3);
lv1.setAdapter(new ArrayAdapter<String>(this, R.layout.list_item_1, s1));
lv2.setAdapter(new ArrayAdapter<String>(this, R.layout.list_item_2, s2));
lv3.setAdapter(new ArrayAdapter<String>(this, R.layout.list_item_3, s3));
}
}
例如如果活动开始,然后有人触摸了第一个列表视图中的第一个元素(您好,这是一个长文本,将有助于测试),则它应该开始选取框。
提前致谢!!
最佳答案
这有效:
lv1.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View arg1, int pos,
long arg3) {
// TODO Auto-generated method stub
Log.e("Child at 0 pos"," "+lv1.getChildAt(pos));
txtv = (TextView)lv1.getChildAt(pos);
txtv.setSelected(true);
}
});
