Question

在android中写了一个menu，但是点击之后没有反应，求教了！

menu部分代码如下：
protected static final int MENU_COMMENT = Menu.FIRST;
protected static final int MENU_COLLECTION = Menu.FIRST+1;
protected static final int MENU_SEARCH= Menu.FIRST+2;
protected static final int MENU_ABOUT = Menu.FIRST+3;
protected static final int MENU_QUIT= Menu.FIRST+4;

public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
menu.add(2,MENU_COMMENT,0,"书评");
menu.add(2,MENU_COLLECTION,0,"我读");
menu.add(2,MENU_SEARCH,0,"搜书");
menu.add(2,MENU_ABOUT,0,"关于");
menu.add(2,MENU_QUIT,0,"退出");
return super.onCreateOptionsMenu(menu);
}

public boolean onOptionsItemMenu(MenuItem item){
//super.onOptionsItemSelected(item);
switch(item.getItemId())
{
case MENU_COMMENT:
actionClickMenuItem1();
case MENU_COLLECTION:
actionClickMenuItem2();
case MENU_SEARCH:
actionClickMenuItem3();
case MENU_ABOUT:
openOptionsDialog();
break;
case MENU_QUIT:
finish();
break;
}
return super.onOptionsItemSelected(item);
}

private void actionClickMenuItem3(){
// TODO Auto-generated method stub
setTitle("搜书");

//Intent intent1 = new Intent(ActivityMain.this, ActivitySearch.class);
//startActivity(intent1);
Intent intent = new Intent();
intent.setClass(ActivityMain.this, ActivitySearch.class);
startActivity(intent);

}

private void actionClickMenuItem2() {
// TODO Auto-generated method stub
setTitle("我读");
Intent intent1 = new Intent(ActivityMain.this, ActivityCollection.class);
startActivity(intent1);
}

private void actionClickMenuItem1() {
// TODO Auto-generated method stub
setTitle("书评");
Intent intent1 = new Intent(ActivityMain.this, ActivityCommentList.class);
startActivity(intent1);

}

private void openOptionsDialog() {
// TODO Auto-generated method stub
new AlertDialog.Builder(this)
.setTitle(R.string.app_about)
.setMessage(R.string.app_about_msg)
.setPositiveButton(R.string.str_ok,
new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub

}
}).show();
}

Answer 1

onOptionsItemMenu这个函数里面的case语句有错，下面是我下的一段代码，你看一下，应该知道你那个是什么错误了。
public boolean onOptionsItemSelected(MenuItem item){
switch (item.getItemId()) {
case 1:
sign = 1;
provinces=new String[]{"工具","关于","退出"};
showSingleChoiceDialog();
return true ;
case 2:
sign = 2;
provincesstep=new String[]{"选择提示音","退出"};
showSingleChoiceDialogStep();
return true;
case 3:
notificationManager.cancel(R.drawable.icon);
System.exit(0);
return true;
}
return false;
}

注意里面的return语句。

Answer 2

public boolean onOptionsItemMenu(MenuItem item){
错了 你加个 @Override 就看到了
用public boolean onOptionsItemSelected(MenuItem item 就可以了

Answer 3

menu.add(2,MENU_COMMENT,MENU_COMMENT,"书评");
其他修改类似

请问下 menu.add()第三项参数不是顺序吗？

追答

嗯，排序

追问

那为什么要改排序呢？
然后按您说的改了也没反应...囧...

追答

调试下，看switch语句有没有运行到
