Android开发listview选中高亮简单实现代码分享
百度了好几种listview选中高亮的办法都太繁琐太不友好,我在无意中发现了一种简单有效的办法,而且代码量极少
源码如下:
MainActivity.java
package com.listviewtest; import android.os.Bundle; import android.app.Activity; import android.graphics.drawable.Drawable; import android.view.View; import android.widget.AdapterView; import android.widget.ArrayAdapter; import android.widget.ListView; import android.widget.AdapterView.OnItemClickListener; public class MainActivity extends Activity { private ListView listview; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); String[] items_text = { "选项一", "选项二", "选项三", "选项四", "选项五" }; listview = (ListView) findViewById(R.id.listView1); listview.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,items_text)); listview.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> arg0, View arg1, int position, long id) { Drawable drawable=getResources().getDrawable(R.drawable.red); listview.setSelector(drawable); } } ); } }
activity_main.xml
<pre name="code" class="html"><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context=".MainActivity" > <ListView android:id="@+id/listView1" android:background="@color/gray" android:layout_width="match_parent" android:layout_height="wrap_content" android:scrollingCache="false" /> </RelativeLayout>
values/strings.xml中添加
<pre name="code" class="html"> <drawable name="red">#ff0000</drawable>
