Listview按键触发选择item改变文字
来源：互联网 发布：smartptt对讲软件下载 编辑：程序博客网 时间：2024/05/17 08:35
做的是智能TV，手机上触屏那套Listview的方式当然就有问题，第一个，首次进入Listview发现条目没有焦点。第二个，使用Listview发现onKeyDown(int keycode,KeyEvent event)不起作用。解决这两个问题，网上找到方法，
第一个问题：
Instrumentation inst = new Instrumentation();
inst.setInTouchMode(false);//listView首次进入无焦点的解决办法。在listview生成前，加入这两句，但是我实验不起作用。后来还是用的这个：
public void recoverFocus(){
listview_ci_debug.requestFocus();
listview_ci_debug.setSelection(0);
}
这个函数的用法对位置有特别要求，就是必须放在ui主activity中调用。放在子类中不起作用，很奇怪。
第二个问题：
public boolean dispatchKeyEvent(KeyEvent event) {
// TODO Auto-generated method stub
boolean bRet = true;
currentIndex = getCurrentIndex();
if(event.getAction()==KeyEvent.ACTION_DOWN && event.getAction() != KeyEvent.ACTION_UP){
switch (event.getKeyCode()){
//你的代码逻辑，比如
case KeyEvent.KEYCODE_DPAD_RIGHT:
break;
}
return bRet;
}
特别注意的是最后要return true；保证按键响应执行。
接下来就是直接贴代码了：
