我想在工具栏中均匀显示所有五个图标。但目前工具栏的左侧只显示一个图标,工具栏内的其余空间为空。我尝试使用名为setupEvenlyDistributedToolbar
的方法管理项目。
我在MainActivity中获得了此代码:
package com.example.timomichel.myapplication;
import android.content.ClipData;
import android.content.Intent;
import android.graphics.Point;
import android.provider.ContactsContract;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.Toolbar;
import android.util.DisplayMetrics;
import android.view.Display;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
public class MainActivity extends AppCompatActivity {
private Toolbar toolbar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.toolbar) ;
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
setupEvenlyDistributedToolbar();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.items, menu);
return true;
}
public void setupEvenlyDistributedToolbar() {
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;
toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.inflateMenu(R.menu.items);
toolbar.setContentInsetsAbsolute(0, 0);
int childCount = toolbar.getChildCount();
int screenWidth = (width/5);
Toolbar.LayoutParams toolbarParams = new Toolbar.LayoutParams(screenWidth, Toolbar.LayoutParams.WRAP_CONTENT);
for (int i = 0; i < childCount; i++) {
View childView = toolbar.getChildAt(i);
childView.setLayoutParams(toolbarParams);
}
}
}
我的MainActivity XML文件:
<?xml version="1.0" encoding="utf-8"?>
<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"
tools:context="com.example.timomichel.myapplication.MainActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!" />
<include layout="@layout/toolbar" />
</RelativeLayout>
以下是工具栏的XML:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@android:color/black">
</android.support.v7.widget.Toolbar>
最后是菜单文件夹中项目的XML:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/profile"
app:showAsAction="always"
android:icon="@drawable/android_icon"
android:title="profile" />
<item
android:id="@+id/friends"
app:showAsAction="always"
android:icon="@drawable/android_icon"
android:title="friends"/>
<item
app:showAsAction="always"
android:icon="@drawable/android_icon"
android:title="maps"/>
<item
app:showAsAction="always"
android:icon="@drawable/android_icon"
android:title="events" />
<item
app:showAsAction="always"
android:icon="@drawable/android_icon"
android:title="Settings" />
</menu>
希望你也能帮我解决这个问题,非常感谢!
