Android 如何在 Dialog 中适配 listview
Android how to fit listview in Dialog
当 ListView 包含超过 12 个 ListItem 时,我无法将 ListView 放入弹出对话框。是否有任何我在这里遗漏的属性,或者我是否必须在后面的代码中自己计算最大大小?
当一切都完美契合时,我的布局看起来像这样:
当我有太多的项目时,你可以看到我的 LinearLayout 在列表视图和按钮下面消失了。
这是我的 Layout.xml

您可以通过两种方式做到这一点:
第一个:
将所有内容或您想要的内容放入 "ScrollView",无论您放置多少项目,您的项目都会滚动。
例如:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- PUT EVERYTHING YOU WANT HERE -->
</ScrollView>
</RelativeLayout>
第二个:
使用适配器和列表项将所有项放入 ListView:
item_list.xml(在 res > layout > New > XML > Layout XML File):
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:layout_margin="20dp"
android:id="@+id/item_text"
android:text="Test"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
你的列表适配器(在 java > yourPackageName > new > Kotlin File/Class):
import android.content.Context
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import android.widget.BaseAdapter
import android.widget.TextView
class ListAdapter (private val context: Context, private val listItems: ArrayList<String>) : BaseAdapter() {
override fun getView(position: Int, convertView: View?, parent: ViewGroup?): View {
val view = LayoutInflater.from(context).inflate(R.layout.item_list, null)
val text = view.findViewById<TextView>(R.id.item_text)
text.text = listItems[position]
return view
}
//It doesn't matter right now
override fun getItem(position: Int): Any {
return ""
}
//It doesn't matter right now
override fun getItemId(position: Int): Long {
return 0
}
override fun getCount(): Int {
return listItems.size
}
}
