設置listview，隔行不一樣style

1新建兩個背景Drawable

even_row.xml

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

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

<solid android:color="#A0A0A0"/>

<padding android:left="3dp" android:top="3dp" android:right="3dp" android:bottom="3dp" />

<stroke android:width="1dp" android:color="#00CC00"/>

</shape>

odd_row.xml

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

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

<solid android:color="#A0A0A0"/>

<padding android:left="3dp" android:top="3dp" android:right="3dp" android:bottom="3dp" />

<stroke android:width="1dp" android:color="#00CC00"/>

</shape>

2建立兩個selectors

listview_selector_event.xml

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

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

<item android:drawable="@drawable/even_row" android:state_enabled="true"/>

<item android:drawable="@drawable/even_row" android:state_pressed="true"/>

<item android:drawable="@drawable/even_row" android:state_focused="true"/>

</selector>

listview_selector_odd.xml

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

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

<item android:drawable="@drawable/odd_row" android:state_enabled="true"/>

<item android:drawable="@drawable/odd_row" android:state_pressed="true"/>

<item android:drawable="@drawable/odd_row" android:state_focused="true"/>

</selector>

3 有了這兩個selector就能夠把咱們背景資源添加到listview上了。

public View getView(int position, View convertView, ViewGroup parent) {

View v = convertView;

PlanetHolder holder = new PlanetHolder();

// First let's verify the convertView is not null

if (convertView == null) {

// This a new view we inflate the new layout

LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

v = inflater.inflate(R.layout.row_layout, null);

// Now we can fill the layout with the right values

TextView tv = (TextView) v.findViewById(R.id.name);

holder.planetNameView = tv;

v.setTag(holder);

if ( position % 2 == 0)

v.setBackgroundResource(R.drawable.listview_selector_even);

else

v.setBackgroundResource(R.drawable.listview_selector_odd);

}

else

holder = (PlanetHolder) v.getTag();

Planet p = planetList.get(position);

holder.planetNameView.setText(p.getName());

return v;

}
