使用String的几个方法

Use the String Resources

In your source code, you can refer to a string resource with the syntax R.string.<string_name>. There are a variety of methods that accept a string resource this way.

For example:

// Get a string resource from your app‘s ResourcesString hello = getResources().getString(R.string.hello_world);

// Or supply a string resource to a method that requires a stringTextView textView = new TextView(this);textView.setText(R.string.hello_world);

In other XML files, you can refer to a string resource with the syntax @string/<string_name> whenever the XML attribute accepts a string value.

For example:

<TextView    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:text="@string/hello_world" />
