Android实现 ScrollView + ListView无滚动条滚动

1. NoScrollListView.java

[java] view
plaincopy

/***

* 自定义ListView子类，继承ListView

* @author Administrator

*

*/

public class NoScrollListView extends ListView {

public NoScrollListView(Context context) {

super(context);

}

public NoScrollListView(Context context, AttributeSet attrs) {

super(context, attrs);

}

public NoScrollListView(Context context, AttributeSet attrs, int defStyle) {

super(context, attrs, defStyle);

}

@Override

public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);

super.onMeasure(widthMeasureSpec, expandSpec);

}

}

2. res > layout > activity_main.xml

[html] view
plaincopy

<?xml version="1.0" encoding="utf-8"?>

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@+id/ScrollView"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:background="#FFF4F4F4"

android:scrollbars="vertical" >

<LinearLayout

android:id="@+id/LinearLayout"

android:gravity="center_horizontal"

android:background="#FFF4F4F4"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:orientation="vertical" >

<TextView

android:id="@+id/textView1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_marginLeft="2dp"

android:layout_marginTop="20dp"

android:text="This's a listView..." />

<!--原： <ListView> -->

<com.example.listviewdemo.NoScrollListView

android:id="@+id/listView1"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:dividerHeight="0.0dip"

android:fadingEdge="none"

android:cacheColorHint="#FFF4F4F4"/>

</LinearLayout>

</ScrollView>

这里注意：原来的<ListView 改为<com.example.listviewdemo.NoScrollListView 。

3.MainActivity

[java] view
plaincopy

private String[] nameList = {"Miley Cyruc","Alice Keys","Jewel","Dublin","Kelly Clarkson",

"Mariah Carey","Sheen","Adele","Avril Lavigne","Taylor Swift"};

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

ListView lv = (ListView) findViewById(R.id.listView1);

ArrayAdapter adapter = new ArrayAdapter(this, android.R.layout.simple_list_item_1, nameList);

lv.setAdapter(adapter);

//lv.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);//选择效果

//listView注册一个元素点击事件监听器

lv.setOnItemClickListener(new OnItemClickListener() {

@Override

public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {

Log.d(TAG, "//:"+MainActivity.this.nameList[arg2]);

Toast.makeText(MainActivity.this, "Hey, "+nameList[arg2], Toast.LENGTH_LONG).show();

}

});

}
