How to get and set string Resource values in android
提问by Trikaldarshi
I've declare a String:
我已经声明了一个String：
<string name="Please">Please Select</string>
in the res/values/Strings.xml. Now I want to access this Stringvalue but what I can get can go till id not value like:
在res/values/Strings.xml. 现在我想访问这个String值，但我能得到的可以一直持续到 id 不值，例如：
int i = findViewById(R.string.Please);
But what I want is just the value of the string Please.
但我想要的只是 string 的值Please。
Thanks for all of your answer but my problem is a little bigger
感谢您的所有回答，但我的问题有点大
What I wanted to do is just to display date with app_name
我想要做的只是用 app_name 显示日期
from all your answers i can get the app_name String but whether I can set This app_name with current date
从你所有的答案中，我可以得到 app_name 字符串，但是我是否可以将这个 app_name 设置为当前日期
<string name="app_name">My app</string>
and also I'm to set my in this way
而且我要以这种方式设置我的
My app(in Left alignment) Date (in right aligment)
and also on start of first activity i want to set app_name and not on every activity;
并且在第一个活动开始时，我想设置 app_name 而不是每个活动；
I think it may work let me try
我认为它可能有效让我试试
setResource().setString(R.string.Please);
but no setResource() method sorry.
但没有 setResource() 方法抱歉。

You cant set a string, its static, and cant be changed at run-time, what you want to do is something like this
你不能设置一个字符串，它是静态的，不能在运行时改变，你想做的是这样的
Calendar cal = Calendar.getInstance();
String date = cal.get(Calendar.DAY_OF_MONTH) + "/" + cal.get(Calendar.MONTH) + "/" + cal.get(Calendar.YEAR);
setTitle(date);
Your trying to set the title as the date right?
您试图将标题设置为日期吗？
To have two titles it is a bit harder, first you need a layout, call this custom_title_1
有两个标题有点难，首先你需要一个布局，称之为custom_title_1
This is the xml code for that layout
这是该布局的 xml 代码
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/screen"
android:layout_width="match_parent" android:layout_height="match_parent"
android:orientation="vertical">
<TextView android:id="@+id/left_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:text="@string/custom_title_left" />
<TextView android:id="@+id/right_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="@string/custom_title_right" />
</RelativeLayout>
Then in your code before you call the UI you need to call this:
然后在调用 UI 之前的代码中，您需要调用它：
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
then set you content view
然后设置你的内容视图
then call this which will set the title:
然后调用这将设置标题：
getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.custom_title_1);
Now you can find the two textViews and set the text:
现在你可以找到两个 textViews 并设置文本：
TextView leftText = (TextView) findViewById(R.id.left_text);
TextView rightText = (TextView) findViewById(R.id.right_text);
Calendar cal = Calendar.getInstance();
String date = cal.get(Calendar.DAY_OF_MONTH) + "/" + cal.get(Calendar.MONTH) + "/" + cal.get(Calendar.YEAR);
String app_name = getString(R.string.app_name);
leftText.setText(app_name);
rightText.setText(date);

String resources are not views. To use a string resource you would do
字符串资源不是视图。要使用字符串资源，你会这样做
@string/Please
