我如何将来自String.xml的getString（）用于MainActivity类？

public class MainActivity extends AppCompatActivity {

    String string = getString(R.string.app_name);

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

    }
}   

Answer 1

在onCreate方法中编写get方法

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    String appName = getString(R.string.app_name);

}
