百度了一大圈,其实也没有好的方法,就是selector的练习~~

老规矩,先上GIF动态图,看个效果,如果符合你的项目或者确定你要了解的内容,再往下看吧:



res\layout\my_select_dialog_multichoice.xml:

<?xml version="1.0" encoding="utf-8"?>
<CheckedTextView
xmlns:android="http://schemas.android.com/apk/res/android"

android:drawableLeft="@drawable/checkbox_style"

android:id="@android:id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?android:attr/listPreferredItemHeight"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textColor="?android:attr/textColorAlertDialogListItem"
android:gravity="center_vertical"
android:ellipsize="marquee">

</CheckedTextView>

<!--文字居中-->
<!--android:textAlignment="center"-->

<!--复选框 左显示-->
<!--android:drawableLeft="?android:attr/listChoiceIndicatorMultiple"-->

<!--复选框右显示(默认位置)-->
<!--android:checkMark="?android:attr/listChoiceIndicatorMultiple"-->

<!--自定义的复选框样式 左显示-->
<!--android:drawableLeft="@drawable/checkbox_style"-->

<!--自定义的复选框样式 (默认位置)-->
<!--android:checkMark="@drawable/checkbox_style"-->res\drawable\checkbox_style.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="@drawable/check_nnn" android:state_checked="false"></item>
<item android:drawable="@drawable/check_nnn" android:state_selected="true"></item>
<item android:drawable="@drawable/check_nnn" android:state_pressed="true"></item>
<item android:drawable="@drawable/check_yyy"></item>
</selector>MainActivity.java:
package com.iwanghang.listviewdemo;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class MainActivity extends AppCompatActivity {

private ListView lv;
private ArrayAdapter<String> adapter;
//private ArrayAdapter<ListData> adapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

// 经典的adndroid.R的item
//adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1);
// 多选item
//adapter = new ArrayAdapter<String>(this,android.R.layout.select_dialog_multichoice);
// 自己写的item 使用CheckedTextView
adapter = new ArrayAdapter<String>(this,R.layout.my_select_dialog_multichoice);
// 单选item (也可以当多选用)
//adapter = new ArrayAdapter<String>(this,android.R.layout.select_dialog_singlechoice);
// 勾选item
//adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_checked);
// 小字体item
//adapter = new ArrayAdapter<String>(this,android.R.layout.simple_gallery_item);

//adapter = new ArrayAdapter<String>(this,R.layout.text_item);
//adapter = new ArrayAdapter<ListData>(this,R.layout.text_item);
lv = (ListView) findViewById(R.id.lv);
lv.setAdapter(adapter);
adapter.add("hello");
adapter.add("hello");
adapter.add("hello");
adapter.add("hello");
adapter.add("hello");
adapter.add("hello");
adapter.add("hello");
adapter.add("hello");
adapter.add("hello");
adapter.add("hello");
adapter.add("hello");
adapter.add("hello");
adapter.add("hello");
adapter.add("hello");
adapter.add("hello");
adapter.add("hello");

//adapter.add(new ListData("android","man",404));
//adapter.add(new ListData("android","woman",388));
//adapter.add(new ListData("android","null",888));

// 其中 多选、单选、勾选 可以用下面2个函数还设置 多选/单选 属性
lv.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE); // 多选
//lv.setChoiceMode(ListView.CHOICE_MODE_SINGLE); // 单选

// checkedTextView = (CheckedTextView) findViewById(R.layout.my_select_dialog_multichoice);
// //checkedTextView.setCheckMarkDrawable(android.R.drawable.arrow_down_float);
//
// //根据数组id得到数组类型
// TypedArray ta = getBaseContext().getTheme().obtainStyledAttributes(new int[]{R.drawable.icon_box_empty});
// //初始化绘制目标
// Drawable indicator = ta.getDrawable(0);
// checkedTextView = new CheckedTextView(this);
// checkedTextView.setText("test1");
// //得到绘制目标后放入选择框中
// checkedTextView.setCheckMarkDrawable(indicator);

// item点击监听
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

// 写法1:
//String name = adapter.getItem(position).getUserName();
//String sex = adapter.getItem(position).getSex();
//int age = adapter.getItem(position).getAge();
//Toast.makeText(MainActivity.this, "你点击了:"+name+" "+sex+" "+age, Toast.LENGTH_SHORT).show();

// 写法2:
//ListData ld = adapter.getItem(position);
//Toast.makeText(MainActivity.this, String.format("%s %s %s",ld.getUserName(),ld.getSex(),ld.getAge()), Toast.LENGTH_SHORT).show();

}
});
}
