strings.xml:

<string name="some_text">Some Text</string>

Activity:

getString(R.string.some_text);

Well you can get String using,

getString(R.string.app_name);

And, you can get string-array using

String arr[] = getResources().getStringArray(R.array.planet);
for (int i = 0; i < arr.length; i++) {
Toast.makeText(getBaseContext(),arr[i], Toast.LENGTH_LONG).show();
}

最佳答案

Put this code in res/values/string.xml

<string-array name="planet">
<item>Mercury</item>
<item>Venus</item>
<item>Earth</item>
<item>Mars</item>
</string-array>

This code to be placed in res/layout/main.xml and remove default widgets present in main.xml.

<ListView android:id="@+id/planet"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:entries="@array/planet"/>
</LinearLayout>

If getString(R.string.app_name); isn't working for you, you can pass context like this:

context.getString(R.string.app_name);

If you have the context of Activity, go with:

getString(R.string.app_name);

If you don't have the context, try below, you can get the context from activity using Constructor.

mContext.getString(R.string.app_name);
