我正在尝试实现自定义标题栏:
这是我的助手类:
import android.app.Activity;
import android.view.Window;
public class UIHelper {
public static void setupTitleBar(Activity c) {
final boolean customTitleSupported = c.requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
c.setContentView(R.layout.main);
if (customTitleSupported) {
c.getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.titlebar);
}
}
}
这是我在onCreate()中称呼它的地方:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setupUI();
}
private void setupUI(){
setContentView(R.layout.main);
UIHelper.setupTitleBar(this);
}
但是我得到了错误:
requestFeature() must be called before adding content
