我尝试了各种解决方案以获得工具栏标题,但它们都没有奏效。喜欢使用和其他人。我的代码出了什么问题。你能建议吗?我得到菜单和他们的选项,但工具栏的标题没有运气。
package jss.customtoolbar;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowTitleEnabled(true);
getSupportActionBar().setTitle("Hello");
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
return super.onCreateOptionsMenu(menu);
}
}
下面是我的style.xml代码:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/miCompose"
android:icon="@mipmap/ic_launcher"
android:title="Compose"
app:showAsAction="ifRoom" />
<item
android:id="@+id/miProfile"
android:title="Profile" />
</menu>
我的主要活动代码:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/colorPrimary"
android:minHeight="?attr/actionBarSize"
android:title="Hello">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
</RelativeLayout>
</android.support.v7.widget.Toolbar>
</LinearLayout>
menu.xml代码:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:orientation="vertical"
tools:context="jss.customtoolbar.MainActivity">
<include
layout="@layout/tool"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
工具栏代码:
$string= 'This is a string? Or an array?';
$array = array_filter(array_map('trim',preg_split("/\b/", $string)));
print_r($array);
和activity_main.xml代码:
Array
(
[1] => This
[3] => is
[5] => a
[7] => string
[8] => ?
[9] => Or
[11] => an
[13] => array
[14] => ?
)
答案 0 :(得分:0)
您可以将标题设置为工具栏以供参考,无需获得支持工具栏。
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setTitle("Hello");
setSupportActionBar(toolbar);
}
工具栏xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
