菜单项不会在actiobar显示 [英] Menu items won't show up in the actiobar

问题描述

更新： 它的工作原理选项卡上，但是在手机上它的重叠由于某种原因，

我有一个关于该菜单项的android一个问题使用的动作条，我有一个自定义的背景为我actiobar（图片），在此设置在code。那块code正常工作。但是，当我尝试添加菜单项，它失败。

我要的很简单，我想有一个按钮，上面写着保存产品为最喜爱的在屏幕的底部，像底动作条。但是，当我尝试添加按钮菜单项不会显示出来，没有什么变化。

日志告诉我onCreateOptionsMenu（）方法实际上是在执行。任何想法？

这是该活动我想要的菜单：

解决方案

如果你想显示在操作栏中的菜单项，将安卓showAsAction的属性在product_menu.xml您的项目;

 ＆LT; XML版本=1.0编码=UTF-8＆GT？;
＆LT;菜单的xmlns：机器人=htt​​p://schemas.android.com/apk/res/android＆GT;
    ＆LT;项目
        机器人：ID =@ + ID / ITEM1
        机器人：标题=保存
        机器人：showAsAction =总是/＆GT;
＆LT; /菜单＆gt;
 

您可以将此属性设置为：

• ifRoom
• 从来没有
• withText
• 总是
• collapseActionView

我希望这可以帮助你！

UPDATE: It works on the tab, but on the phone it's overlayed for some reason

I have a question regarding the menu items android uses for the ActionBar, I have a custom background for my actiobar (a picture) and set it in the code here. That piece of code works fine. But when I try to add a menu item, it fails.

What I want is fairly simple, I want a button that says "save product as favorite" at the bottom of the screen, like the bottom-actionbar. But when I try to add the button as menu item it won't show up, nothing changes.

The log tells me the onCreateOptionsMenu() method is in fact executed. Any ideas?

This is the activity I want the menu for:

package com.x;


import java.util.ArrayList;
import java.util.HashMap;

import android.app.ActionBar;
import android.app.ActionBar.Tab;
import android.app.Activity;
import android.app.LocalActivityManager;
import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.drawable.BitmapDrawable;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;
import android.widget.TextView;

import com.x.R;
import com.x.products.fragments.*;
import com.x.tasks.ZoekQueryTask;
import com.x.util.Helper;
import com.x.util.UnscaledBitmapLoader;


public class ProductActivity extends Activity {

    private Bundle save;

    /** Called when the activity is first created. */
    @SuppressWarnings("rawtypes")
    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.product);

        @SuppressWarnings("deprecation")
        LocalActivityManager manager = new LocalActivityManager(this, false);

        Helper helper = new Helper();
        save = null;
        String id = (String) getIntent().getExtras().get("id");
        String score = (String) getIntent().getExtras().get("score");
        String profileId = (String) getIntent().getExtras().get("profileId");

   //     String id = "138946";
    //    String profileId = "28";
    //    String score = "100%";
        String query  = "SELECT * FROM products WHERE id = "+id;
        ArrayList<HashMap> result = null;

        try {
            ZoekQueryTask zoekQueryTask = new ZoekQueryTask(query);
            result = zoekQueryTask.getResults();
        }

        catch(Exception e) {
            Log.e("Afgevangen error", e.getMessage());
        }



        TabHost tb = (TabHost) findViewById(R.id.tabs);
        manager.dispatchCreate(savedInstanceState);
        tb.setup(manager);



        Intent info = new Intent();
        info.setClass(this, InfoFragment.class);
        info.putExtra("result", result);
        info.putExtra("profileId", profileId);

        TabSpec tsInfo = tb.newTabSpec("info");
        tsInfo.setContent(info);
        tsInfo.setIndicator("info");



        Intent specs = new Intent();
        specs.setClass(this, SpecsFragment.class);
        specs.putExtra("result", result);

        TabSpec tsSpecs = tb.newTabSpec("specs");
        tsSpecs.setContent(specs);
        tsSpecs.setIndicator("specs");



        Intent prijs = new Intent();
        prijs.setClass(this, PrijsFragment.class);
        prijs.putExtra("result", result);

        TabSpec tsPrijs = tb.newTabSpec("Prijs");
        tsPrijs.setContent(prijs);
        tsPrijs.setIndicator("Prijs");

        TabSpec tsFotos = tb.newTabSpec("Fotos");
        tsFotos.setContent(info);
        tsFotos.setIndicator("Fotos");


        tb.addTab(tsInfo); 
        tb.addTab(tsSpecs);
        tb.addTab(tsPrijs);
        tb.addTab(tsFotos);



            final ActionBar actionBar = getActionBar(); 
            actionBar.setDisplayShowHomeEnabled(false);
            actionBar.setDisplayShowTitleEnabled(false);


            Bitmap bm = UnscaledBitmapLoader.loadFromResource(getResources(), R.drawable.logo, null);
            BitmapDrawable background = new BitmapDrawable(this.getResources(), bm);
            background.setTileModeX(android.graphics.Shader.TileMode.CLAMP); 
            actionBar.setBackgroundDrawable(background);



            TextView nameText = (TextView) findViewById(R.id.name);
            TextView scoreText = (TextView) findViewById(R.id.score);

            nameText.setText(result.get(0).get("name").toString());
            scoreText.setText(score);

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        Log.i("hallo", "hoi");
        inflater.inflate(R.layout.product_menu, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle item selection
        switch (item.getItemId()) {
            case R.id.save:
                Log.i("menu", "werkt");
                return true;
            default:
                return super.onOptionsItemSelected(item);
        }
    }

}

This is the menu XML:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >

    <item android:id="@+id/save"
          android:title="Opslaan in favorieten" >

    </item>
</menu>

解决方案

If you want to show your menu item in the action bar, set the android:showAsAction property of your item in product_menu.xml;

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item 
        android:id="@+id/item1" 
        android:title="Save"
        android:showAsAction="always" />
</menu>

You can set this property to:

• ifRoom
• never
• withText
• always
• collapseActionView

I hope this helps you!
