我想自定义android对话框,使其看起来像下面的浮动对话框,建议在https://material.google.com/components/dialogs.html#dialogs-simple-dialogs
我尝试创建一个DialogFragment,其中onCreateDialog返回一个Dialog,其视图的根目录是CardView.But无法获得预期的结果。我可以就如何实现这一点提出一些建议吗?
我的布局看起来像这样,
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center|top"
card_view:cardElevation="5dp"
card_view:cardPreventCornerOverlap="false">
//Contents come here
</android.support.v7.widget.CardView>
&#13;
并在代码中
public Dialog onCreateDialog(Bundle savedInstanceState) {
Dialog dialog = new Dialog(getActivity());
View view = LayoutInflater.from(getActivity()).inflate(R.layout.dialog_font_selection,null,false);
dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(view);
float width = (I am getting screen width here) * .80f;
dialog.getWindow().setLayout((int) width, ViewGroup.LayoutParams.WRAP_CONTENT);
return dialog;
}`

AlertDialog.Builder mydialog = new AlertDialog.Builder( context);
mydialog.setTitle("Set backup accounts");
mydialog.setItems(CharSequence[] items, OnClickListener);
mydialog.show();
mydialog.setContentView(R.layout.mydialogLayout);
这在您的活动/片段中。所以声明你的布局如下:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center_horizontal">
<TextView
android:id="@+id/myID1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
之后,如果您想要处理点击,请执行以下操作:
TextView myView1 = (TextView) mydialog.findViewById(myID1);
myView1.setOnClickListener(...);
