我在活动中有一个带有页脚的列表视图。我想要做的是以编程方式向页脚添加textview。
Activity.java , Activity.xml , footer.xml
Activty.java的一部分onCreate()方法:
LinearLayout layout = (LinearLayout)View.inflate(this, R.layout.footer, null);
TextView tv = new TextView(this);
tv.setText("added text");
tv.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
tv.setVisibility(View.VISIBLE);
layout.addView(tv);
View footer = getLayoutInflater().inflate(R.layout.refer_footer, null, false);
listView.addFooterView(footer);
listView.setAdapter(adapter);
Activity.xml:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
xmlns:android="http://schemas.android.com/apk/res/android">
<ListView
android:id="@+id/referList"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
footer.xml:
<LinearLayout
android:id="@+id/footer_layout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:gravity="center"
xmlns:android="http://schemas.android.com/apk/res/android">
</LinearLayout>
但我无法在应用中添加textview。有人请帮忙。

尝试创建TextView实例并将其添加到ListView适配器。
ListView listView = .. //create your list, or inflate it from xml...
TextView footerView = new TextView(activity.getApplicationContext());
listView.addFooterView(footerView);
listView.setAdapter(myAdapter);
