我该如何调整Android的工具栏菜单/图标在谷歌地图应用程序左侧是怎样的？ [英] How can I align Android Toolbar menu/icons to the left like in Google Maps app?

问题描述

下面是谷歌地图工具栏的截图。

Here is a screenshot of Google Maps Toolbar.

正如你所看到的图标对齐，而不是右左（默认行为）。我试着加入机器人：layout_gravity =左和android：重力=左的工具栏，但没有奏效。也试图加入一个内部的LinearLayout（相同重力值）到工具栏，但没有任何工作。有任何想法吗？我希望能够利用从从头重新一切使用工具栏常规的Andr​​oid窗口小部件菜单代替。

As you can see icons are aligned to the left instead of right (default behavior). I've tried adding android:layout_gravity="left" and android:gravity="left" to the toolbar but it didn't work. Also tried adding an internal LinearLayout (with same gravity values) to the Toolbar but didn't worked either. Any ideas? I want to be able to use a regular Android menu with the Toolbar widget instead of recreating everything from the scratch.

推荐答案

有些挣扎后，挖掘在Android的工具栏code，我设法使它工作。基本上，这个想法是增加一个新的android.support.v7.widget.ActionMenuView作为工具栏的孩子，将其重心顶部|开始，然后添加菜单，在活动的行动功能表视图。这里是code：

After some struggling and digging in Android Toolbar code I managed to make it work. Basically, the idea is to add a new android.support.v7.widget.ActionMenuView as child of the Toolbar, set its gravity to top|start, and then add the menu to that action menu view in your Activity. Here is the code:

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/tToolbar"
    android:layout_height="200dp"
    android:layout_width="match_parent"
    android:minHeight="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    android:gravity="top|start"
    app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light">

    <android.support.v7.widget.ActionMenuView
        android:id="@+id/amvMenu"
        android:layout_width="wrap_content"
        android:layout_height="?attr/actionBarSize"/>
</android.support.v7.widget.Toolbar>

my_activity.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!--Toolbar-->
    <include
        android:id="@+id/tToolbar"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        layout="@layout/my_toolbar" />
</RelativeLayout>

MyActivity.java

import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.widget.ActionMenuView;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;

public final class MyActivity extends ActionBarActivity {
  private ActionMenuView amvMenu;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // this layout includes the custom toolbar my_toolbar.xml
    setContentView(R.layout.my_activity);

    Toolbar t = (Toolbar) findViewById(R.id.tToolbar);
    amvMenu = (ActionMenuView) t.findViewById(R.id.amvMenu);
    amvMenu.setOnMenuItemClickListener(new ActionMenuView.OnMenuItemClickListener() {
      @Override
      public boolean onMenuItemClick(MenuItem menuItem) {
        return onOptionsItemSelected(menuItem);
      }
    });

    setSupportActionBar(t);
    getSupportActionBar().setTitle(null);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
  }

  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    // use amvMenu here
    inflater.inflate(R.menu.my_activity_menu, amvMenu.getMenu());
    return true;
  }

  @Override
  public boolean onOptionsItemSelected(MenuItem item) {
    // Do your actions here
    return true;
  }
}
