Dialog with list view and message
I need to create dialog with b开发者_高级运维oth ListView and message, however according to http://code.google.com/p/android/issues/detail?id=10948 it is not possible with standard AlertDialog. So I've decided to create custom view with text and listview, and attach it to dialog.
However, my list view is drawn empty. Here is java code:
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Hello, title!");
LayoutInflater factory = LayoutInflater.from(this);
View content = factory.inflate(R.layout.dialog, null);
ListView lv = (ListView) content.findViewById(R.id.list);
lv.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_single_choice, ITEMS));
lv.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
builder.setView(content).setPositiveButton("OK", this).setNegativeButton("Cancel", this);
AlertDialog alert = builder.create();
alert.show();
Also I have:
final String[] ITEMS = new String[] { "a", "b", "c" };
and here is dialog layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Hello, text!" />
<ListView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/list"
></ListView>
</LinearLayout>
Here is result:
Any help is greatly appreciated. Thanks!
You are missing android:orientation="vertical"
in linearlayout.
Your xml will be
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Hello, text!" />
<ListView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/list"
></ListView>
</LinearLayout>
set orientation is vertical like
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Hello, text!" />
<ListView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/list"
></ListView>
</LinearLayout>
in your layout
