Question

我想在动作栏中显示一些按钮，但它们只是不显示我已经使用片段成功实现了导航抽屉和viewpager 显示菜单充气器和操作栏按钮的实现也已完成，但它们不会显示

菜单/ main.xml中的

我添加了app：showAsAction =＆＃34; always＆＃34;但它仍然不会出现

这是

和menu / main.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context="com.Blog.gkgyan.MainActivity" >

    <item
        android:id="@+id/action_settings"
        android:orderInCategory="100"
        android:title="@string/action_settings"
        app:showAsAction="never"/>

    <item
        android:id="@+id/action_share"
        android:icon="@drawable/ic_action_share"
        android:orderInCategory="101"
        android:title="@string/action_share"
        app:showAsAction="always" />

    <item
        android:id="@+id/action_rate"
        android:icon="@drawable/ic_action_important"
        android:orderInCategory="101"
        android:title="@string/action_rate"
        app:showAsAction="always"/>

</menu>

我要在 detailactivity.java 的操作栏中显示action_share和Action_rate按钮，尝试在此页面上无效的任何内容

然而它在main activity.java中完全正常工作

这是代码

import android.support.v7.app.ActionBarActivity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.Button;

public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


    }
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // TODO Auto-generated method stub

        Intent intent = null;
        switch (item.getItemId()) {
        case R.id.action_rate:
            String webpage = "http://developer.android.com/index.html";

            intent = new Intent(Intent.ACTION_VIEW, Uri.parse(webpage));
            startActivity(intent);
            break;

        case R.id.action_share:
            intent = new Intent();
            intent.setAction(Intent.ACTION_SEND);
            intent.putExtra(Intent.EXTRA_TEXT, "Hello from Hansel and Petal!");
            intent.setType("text/plain");
            startActivity(intent);
            break;

        default:
            break;
        }
        return super.onOptionsItemSelected(item);
    }


    public void latestActivity(View v){
        //Intent intent = new Intent(this, SplashActivity.class);
        Intent intent = new Intent(this, GkcategoryListActivity.class);
        startActivity(intent);
        overridePendingTransition(R.anim.slide_in, R.anim.slide_out);

    }


}

这是片段活动或导航抽屉的问题任何帮助都会很棒请提及我的代码应该在哪里进行更改

Android操作栏按钮不会显示带有fragment活动的导航抽屉
