android - 如何将对话框窗口包装到内容中？

Question

我正在开发一个对话框，它应该缩小到它的内容，所以，我想在普通 View 中获得类似 wrap_content 的行为，但对于普通的 Dialog . 这就是我想在对话框窗口中显示的内容

在对话窗口中应该是这样的

但这是我实际得到的

你能告诉我我做错了什么吗？

在此先感谢您。

这是我的代码

...
final Dialog dialog = new Dialog(this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); 
dialog.setContentView(R.layout.advanced_options);
dialog.setTitle(titleId);

// Stuff referred to builder
AlertDialog.Builder builder ...
...

int type = WindowManager.LayoutParams.TYPE_INPUT_METHOD;
WindowManager.LayoutParams w_layout_params = new WindowManager.LayoutParams(type);

dialog.getWindow().setAttributes(w_layout_params );
...
builder.create();
dialog.show();

advanced_options.xml 布局

Answer 1

将RelativeView的宽度更改为match_parent

您正在寻找的是 match_parent 的行为。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/relLayout_advancedOptions"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="@drawable/border_advanced_options"
android:divider="?android:listSeparatorTextViewStyle"
android:showDividers="" > 

Note: wrap_content in android specifies the view to use as little space as needed and that is the behavior you're getting.
