你好,以下代码将使用full创建一个界面,其中包含一个或两个ListView,最终跨越整个屏幕的两行。Java文件如下:
public class DoubleListView extends Activity {
ListView listView,listView2;
String[] titles = {"List 1 title1","List 1 title2","List 1 title3","List 1 title4","List 1 title5","List 1 title6","List 1 title7","List 1 title8","List 1 title9"};
String[] titles2 = {"List 2 title1","List 2 title2","List 2 title3","List 2 title4","List 2 title5","List 2 title6","List 2 title7","List 2 title8","List 2 title9"};
WindowManager wm;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
wm = (WindowManager)getSystemService(Context.WINDOW_SERVICE);
int height = wm.getDefaultDisplay().getHeight();
listView = new ListView(this);
listView.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,height/2-15));
listView.setAdapter(new CustomListAdapetr(this, titles));
listView2 = new ListView(this);
listView2.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,height/2));
listView2.setAdapter(new CustomListAdapetr(this, titles2));
((LinearLayout)findViewById(R.id.mailLayout)).addView(listView);
((LinearLayout)findViewById(R.id.mailLayout)).addView(listView2);
}
public class CustomListAdapetr extends BaseAdapter{
private Context mContext;
private String[] list;
public CustomListAdapetr(Context context, String[] titles) {
mContext = context;
list = titles;
}
@Override
public int getCount() {
return list.length;
}
@Override
public Object getItem(int position) {
return list[position];
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
CustomView cv;
if (convertView == null) {
cv = new CustomView(mContext,""+list[position]);
}
else {
cv = (CustomView) convertView;
cv.setTitle(list[position]);
}
return cv;
}
}
private class CustomView extends LinearLayout {
public CustomView(Context context, String itemName) {
super(context);
this.setOrientation(HORIZONTAL);
mTitle = new TextView(context);
mTitle.setText(itemName);
mTitle.setTextSize(25);
addView(mTitle, new LinearLayout.LayoutParams(200, LayoutParams.WRAP_CONTENT));
}
public void setTitle(String title) {
mTitle.setText(title);
}
private TextView mTitle;
}
}
而 XML 文件如下:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/mailLayout">
</LinearLayout>
尝试以下方法来获得您想要的界面。
