如何在Android中获取菜单项的Android ID？

Question

有没有办法获取菜单项的Android ID？我可以看到getTitle()但不是getId().我对ID值"menu_printer_settings"而不是标题值"printer_settings"和菜单项ID(getItemId())感兴趣.我需要此ID才能使我的Monkey Talk脚本也适用于本地化版本.

<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
    android:id="@+id/menu_printer_settings"        
    android:title="@string/printer_settings"
/>

Answer 1

解决方法1:

MenuItem item

String[] id = getResources().getResourceName(item.getItemId()).split("\\/");

然后访问id [1]

溶液2:

使用titleCondensed匹配id,例如

<menu>
            <item android:id="@+id/myid"
                  android:title="some menu title"
                  android:titleCondensed="myid"/>
...
</menu>

然后

String selectedMenuIdString = (String) item.getTitleCondensed();

我更喜欢解决方案1,因为我不必重复ID名称.

希望这可以帮助.关心史蒂夫

试试这个:

public boolean onOptionsItemSelected(MenuItem item) {

            switch (item.getItemId()) {

            case R.id.menu_printer_settings:
                    //do what you want  
                    break;
                }
}

通过获取包的所有字段解决了这个问题

        Map<Integer, String> idMap = new HashMap<Integer, String>();
        Class<?> r;
        String rClass = activity.getBaseContext().getApplicationContext().getPackageName()
                + ".R$id";
        try {
            r = Class.forName(rClass);
        } catch (ClassNotFoundException e1) {
            Log.log("Unable to load " + rClass + ": " + e1.getMessage());
            return idMap;
        }
        for (Field f : r.getFields()) {
            int val;
            try {
                val = f.getInt(null);
            } catch (Exception e) {
                throw new IllegalStateException("Unable to get value for " + f.getName() + ": "
                        + e.getMessage());
            }
            idMap.put(val, f.getName());

        }
