问题描述
无法更改我的工具栏上的文本.我已经进行了搜索,但是没有看到结果.
Unable to get the text on my toolbar to change. I have done a tone of searching but I am seeing no results.
我尝试了很多事情组合,但也许会弹出. 这是我为活动尝试的最后一件事的代码.
I have tried so many combinations of things but maybe something will pop out. Here is the code for the last thing I have tried for my activity.
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbarCustom);
TextView textView = (TextView) toolbar.findViewById(R.id.toolbarTextView);
textView.setText("String");
这是我的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_item_action"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.example.carson.tryeverything.ItemActionActivity"
android:orientation="vertical"
>
<android.support.v7.widget.Toolbar
android:id="@+id/toolbarCustom"
android:layout_width="match_parent"
android:layout_height="?actionBarSize"
android:background="?attr/colorPrimary"
>
<TextView
android:id="@+id/toolbarTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:ellipsize="end"
android:gravity="center"
android:maxLines="1"
android:text="Line one"
android:textAppearance="@android:style/TextAppearance.WindowTitle"
android:visibility="visible" />
</android.support.v7.widget.Toolbar>
<FrameLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="4dp"
android:layout_marginRight="4dp"
android:layout_marginBottom="6dp"
android:layout_marginTop="0dp"
/>
</FrameLayout>
</LinearLayout>
android:textAppearance="@android:style/TextAppearance.WindowTitle"
android:visibility="visible" />
</android.support.v7.widget.Toolbar>
最后这是我的清单文件.大概需要清洁
Lastly here is my Manifest File. Probably needs a little cleaning
<application
android:name="android.support.multidex.MultiDexApplication"
android:allowBackup="true"
android:icon="@mipmap/icon2"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity
android:name=".MainActivity"
android:theme="@style/AppTheme.NoActionBar"/>
<activity
android:name=".SplashScreen"
android:label="@string/app_name"
android:theme="@android:style/Theme.Translucent.NoTitleBar"
>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="no spoilers" />
</intent-filter>
</activity>
<activity android:name=".ItemActionActivity"
android:theme="@style/AppTheme.NoActionBar"
/>
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="@string/google_maps_key" />
<activity
android:name=".MapsActivity"
android:label="@string/title_activity_maps"/>
</application>
我有三个活动,飞溅,主屏幕有2打列表视图选项,然后是最后一个活动屏幕,我希望工具栏根据您单击的位置显示自定义标题.
I have three activities, the Splash, the main screen which has 2 dozen listview options and then the final activity screen where I want the toolbar to show a custom title depending on which you click on.
推荐答案
您忘记设置此项:
setSupportActionBar(toolbar);
和这个:
getSupportActionBar().setDisplayShowTitleEnabled(false);
您的活动类似:
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbarCustom);
setSupportActionBar(toolbar);
TextView textView = (TextView)toolbar.findViewById(R.id.toolbarTextView);
textView.setText("String");
getSupportActionBar().setDisplayShowTitleEnabled(false);
