我有一个LinearLayout,其可见性直接受到TextView点击的影响。此LinearLayout内部动态添加了更多TextView。我的LinearLayout viewQuickLinks
开始时已经消失了。在我的oncreate中,我调用addQuickLinks
,然后将几个TextView添加到LinearLayout。这些TextView都没有设置可见性。我单击TextView将LinearLayout更改为可见,并添加空格,但没有TextView。
我的xml文件(只是为了在滚动视图中添加一个注释):
<TextView
android:id="@+id/textQuickLinksTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:drawableRight="@drawable/navigation_expand"
android:text="@string/quick_links_title"
android:textSize="25sp"
android:visibility="visible" />
<LinearLayout
android:id="@+id/viewQuickLinks"
android:layout_width="fill_parent"
android:layout_height="1dip"
android:visibility="gone"
android:orientation="vertical" />
将LinearLayout更改为可见并消失:
private void setUpQuickLinks() {
final TextView quickLinksTitleText = (TextView) findViewById(R.id.textQuickLinksTitle);
quickLinksTitleText.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
LinearLayout viewQuickLinks = (LinearLayout) findViewById(R.id.viewQuickLinks);
if (viewQuickLinks.getVisibility() == View.VISIBLE){
viewQuickLinks.setVisibility(View.GONE);
quickLinksTitleText.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.navigation_expand, 0);
}
else{
viewQuickLinks.setVisibility(View.VISIBLE);
quickLinksTitleText.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.navigation_collapse, 0);
}
}
});
quickLinksClickListeners();
}
为什么当LinearLayout可见时TextViews不会出现?
感谢您的帮助!
答案 0 :(得分:1)
尝试将android:layout_height
更改为fill_parent
。为什么是1浸?
