Question

我在ActionBar中有3个按钮。一个在左边并使用它将另一项活动称为抽屉。另外两个按钮在右边 Actionbar的一面但他们没有工作。

这是我的菜单文件： -

 <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.example.bottomtabs.FirstActivity" >


   <item
        android:id="@+id/action_settings"
        android:orderInCategory="100"
        android:title="@string/action_settings"
        android:icon="@drawable/like"/>

    <item
        android:id="@+id/menu_settings"
        android:orderInCategory="100"
        android:showAsAction="always"
        android:icon="@drawable/search"
        android:title="menu_settings"/> 

    <item android:id="@+id/action_search"
          android:title="Search"
          android:icon="@drawable/notifications"
          android:showAsAction="always"/>


</menu>

这是我正在使用它的活动。

 public class FirstActivity extends FragmentActivity {

    private FragmentTabHost mTabHost;
    String getselectevalue;


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


        getActionBar().setDisplayHomeAsUpEnabled(true);

        // mTabHost = new FragmentTabHost(this);
        // mTabHost.setup(this, getSupportFragmentManager(),
        // R.id.menu_settings);

        getselectevalue = getIntent().getExtras().getString("selectedVlaue");

        Log.d("got the value here", getselectevalue);

        mTabHost = (FragmentTabHost) findViewById(android.R.id.tabhost);
        mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);

        Bundle b = new Bundle();
        b.putString("key", "Simple");
        mTabHost.addTab(mTabHost.newTabSpec("Post").setIndicator("Post"),Fragment1.class, b);
        //
        //mTabHost.addTab(mTabHost.newTabSpec("Post").setIndicator("", getResources().getDrawable(R.drawable.post_selected),FirstActivity.class));

        b = new Bundle();
        System.out.print("hello git");
        b.putString("key", "Contacts");
        mTabHost.addTab(mTabHost.newTabSpec("Profile").setIndicator("Profile"),Fragment2.class, b);
        b = new Bundle();
        b.putString("key", "Custom");
        mTabHost.addTab(mTabHost.newTabSpec("Chat").setIndicator("Chat"),Fragment3.class, b);

        b = new Bundle();
        b.putString("key", "Custom");
        mTabHost.addTab(mTabHost.newTabSpec("Event").setIndicator("Event"),Fragment3.class, b);

        b = new Bundle();
        b.putString("key", "Custom");
        mTabHost.addTab(mTabHost.newTabSpec("Shop").setIndicator("Shop"),Fragment3.class, b);
        // setContentView(mTabHost);

        if(getselectevalue.equalsIgnoreCase("0")){

        mTabHost.setCurrentTab(0);

        }else{

            mTabHost.setCurrentTab(1);
        }
    }

    @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 onMenuItemSelected(int featureId, MenuItem item) {

        int itemId = item.getItemId();
        switch (itemId) {
        case android.R.id.home:

             Toast.makeText(this, "home pressed", Toast.LENGTH_LONG).show();
             Intent slide = new Intent(FirstActivity.this,Slide.class);

             startActivity(slide);
             overridePendingTransition(R.anim.pull_in_left, R.anim.push_out_right);

            break;
        case R.id.action_settings:

             Toast.makeText(this, "plzzzz start working", Toast.LENGTH_LONG).show();

            break;


        }

        return true;
    }

    @Override
    public boolean onPrepareOptionsMenu(Menu menu){
        menu.findItem(R.id.action_settings).setEnabled(true);

        return super.onPrepareOptionsMenu(menu);
    }

    @Override
    public void onBackPressed() {
     super.onBackPressed();
     overridePendingTransition(R.anim.pull_in_right, R.anim.push_out_left);
    }


}

请帮我解决一下。非常感谢。

Answer 1

~~将onMenuItemSelected()重命名为onOptionsItemSelected()。~~

使用onMenuItemSelected()方法替换onOptionsItemSelected()。除了重命名方法之外，还需要删除int featureId参数。

Answer 2

最初这个过于复杂，无法理解，但经过简短的介绍与@BHARGAV和@COMMONSWARE的讨论，我试着理解了 Actionbar和Menu的行为。我在代码中做了一些更改开始像我一样的魅力。

以下是我在代码中所做的更改。

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    int itemId = item.getItemId();
    switch (itemId) {
    case android.R.id.home:

         Toast.makeText(this, "home pressed", Toast.LENGTH_LONG).show();
         Intent slide = new Intent(FirstActivity.this,Slide.class);

         startActivity(slide);
         overridePendingTransition(R.anim.pull_in_left, R.anim.push_out_right);
         return true;


    case R.id.menu_settings:

         Toast.makeText(this, "plzzzz start working", Toast.LENGTH_LONG).show();
         return true;
    default:
        return super.onOptionsItemSelected(item);
    }


}

@Override
public boolean onPrepareOptionsMenu(Menu menu){
    menu.findItem(R.id.menu_settings).setEnabled(true);

    return super.onPrepareOptionsMenu(menu);
}
