① android wheelview 怎么自定义样式
*
* @param index the item index
* @return the wheel item text or null
*/
public String getItem(int index);
/**
* Gets maximum item length. It is used to determine the wheel width.
* If -1 is returned there will be used the default wheel width.
*
* @return the maximum item length or -1
*/
public int getMaximumLength();
}
② 谁有横向的wheelview-Android开发问答
这是安卓自带的日期选择控件如果你想自己实现的话,有个开源的框架,叫wheelView项目地址/wangjiegulu/WheelView实现的效果就是这样的
③ android 怎样用HorizontalScrollView左右弹性的菜单
{
SlidingMenumSlidingMenu;
@Override
protectedvoidonCreate(Bundlearg0){
super.onCreate(arg0);
setContentView(R.layout.main);
DisplayMetricsdm=newDisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
mSlidingMenu=(SlidingMenu)findViewById(R.id.slidingMenu);
mSlidingMenu.setAlignScreenWidth((dm.widthPixels/5)*2);
ViewleftView=getLayoutInflater().inflate(R.layout.left_menu,null);
ViewrightView=getLayoutInflater().inflate(R.layout.right_menu,null);
ViewcenterView=getLayoutInflater().inflate(R.layout.center,null);
mSlidingMenu.setLeftView(leftView);
mSlidingMenu.setRightView(rightView);
mSlidingMenu.setCenterView(centerView);
ButtonshowLeftMenu=(Button)centerView.findViewById(R.id.center_left_btn);
showLeftMenu.setOnClickListener(this);
ButtonshowRightMenu=(Button)centerView.findViewById(R.id.center_right_btn);
showRightMenu.setOnClickListener(this);
}
@Override
publicvoidonClick(Viewv){
//TODOAuto-generatedmethodstub
switch(v.getId()){
caseR.id.center_left_btn:
mSlidingMenu.showLeftView();
break;
caseR.id.center_right_btn:
mSlidingMenu.showRightView();
break;
default:
break;
}
}
}
④ 关于Android wheelview控件的错乱问题
setVisibleItems(int count)
把count设成单数就可以了
⑤ android wheelview为什么只能展示一个
将布局文件转换成视图,再从中获取那个TextView,再设置监听，LayoutInflaterinflater=LayoutInflater.from(this);Viewview=inflater.inflate(R.layout.xxxxx,null);TextViewtv=(TextView)view.findViewById(R.id.tv_xx);tv.setOnXXXXXXX
⑥ android wheelview样式怎么改
android wheelview样式的话，可以写好xml，然后倒入：
Demo
Use the WheelView as a View, java and XML are both supported.
Java:
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main)
WheelView wheelView = (WheelView) findViewById(R.id.wheelview);
wheelView.setWheelAdapter(new ArrayWheelAdapter(this)); // 文本数据源
wheelView.setSkin(WheelView.Skin.Common); // common 皮肤
wheelView.setWheelData( ?); // 数据集合
}
}
XML:
<com.wx.wheelview.widget.WheelView
android:id="@+id/wheelview"
android:layout_width="match_parent"
android:layout_height="wrap_content" />

⑧ android 怎么得到wheelview的值
TextView text=(TextView)findViewById(R.id.textview01); String s=text.getText().toString().trim(); Intent myIntentDial=new Intent("android.intent.action.CALL",Uri.parse("tel:"+s)); startActivity(myIntentDial);
