处理相同的导航抽屉，但更改每个活动的标题文本

Question

我们是否可以在每项活动中使用相同的导航抽屉，但标题文字会有变化？例如，我有两个活动，我的家庭活动将显示标题文本作为主页，我的“关于我们”活动将显示“关于我们”标题文本，但所有活动都将具有相同的导航设置。

BaseActivity

@TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR2)

protected LinearLayout fullLayout;
protected FrameLayout actContent;

@Override
public void setContentView(final int layoutResID) {
    fullLayout= (LinearLayout) getLayoutInflater().inflate(R.layout.home, null); // Your base layout here
    actContent= (FrameLayout) fullLayout.findViewById(R.id.content_frame);
    getLayoutInflater().inflate(layoutResID, actContent, true); // Setting the content of layout your provided to the act_content frame
    super.setContentView(fullLayout);
    // here you can get your drawer buttons and define how they should behave and what must they do, so you won't be needing to repeat it in every activity class

    prepareListData();

    if (android.os.Build.VERSION.SDK_INT > 9) {
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);
