一.在配置文件采用自定义Style方法去除Actionbar

<resources>
<style name="MyTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item> <!--去除Actionbar-->
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>

<!--toolbar菜单颜色设置-->
<item name="android:textColorSecondary">#ffff</item>
</style>
</resources>

二.XML文件中添加Toolbar

<android.support.v7.widget.Toolbar
android:id="@+id/tb_id"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:background="?attr/colorPrimary"
app:titleTextColor="@color/colorwhite"
></android.support.v7.widget.Toolbar>

三.在java代码中添加Toolbar

public class MainActivity extends AppCompatActivity {

    @Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initTools();
}
//添加Toolbar
private void initTools() {
android.support.v7.widget.Toolbar mtoolbar=findViewById(R.id.tb_id);
    //设置Toolbar菜单点击事件
mtoolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem menuItem) {
switch (menuItem.getItemId()) {
case R.id.one: {
Toast.makeText(MainActivity.this, "我是1", Toast.LENGTH_SHORT).show();
break;
}
case R.id.two: {
Toast.makeText(MainActivity.this, "我是2", Toast.LENGTH_SHORT).show(); break;
}
case R.id.three: {
Toast.makeText(MainActivity.this, "我是3", Toast.LENGTH_SHORT).show(); break;
}
}
return true;
}
});
setSupportActionBar(mtoolbar);
}
// 创建Toolbar菜单
//R.menu.menu是一个定义菜单选项的XMl文件,在第四步中说明
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu,menu);
return super.onCreateOptionsMenu(menu);
}
}

四.menu选项菜单选项设置

  通过在res目录下新建menu目录,并在该目录下添加Menu resourse file(其实就是一个XML文件),然后就可以定义想要的选项.

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