自定义对话框太小了

Question

我有一个实现自定义对话框的android活动。应用程序运行正常，但对话框太小，我想显示一个更大的对话框。我怎样才能实现这一点？ 这是我的布局xml

    android:layout_height="wrap_content"
    android:background="@drawable/blue_button"
    android:text="Buy" />

这是我的输出。我想增加对话框的宽度和高度。

我的java文件

public class MyDialogFragment extends DialogFragment {

public MyDialogFragment() {

}

private EditText mEditText;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.dialogfragment, container);
    // mEditText = (EditText) view.findViewById(R.id.txt_your_name);
    // getDialog().setTitle("Hello");
    getDialog().requestWindowFeature(Window.FEATURE_NO_TITLE);

    return view;
}
}

Answer 1

在运行时更改对话框维度：

yourDialog.show();
yourDialog.getWindow().setLayout((6 * width)/7, LayoutParams.WRAP_CONTENT);

你可以为这两个维做到这一点，在我的例子中我只改变了宽度。 希望它有所帮助！

修改

我忘了提到我的宽度：

DisplayMetrics metrics = getResources().getDisplayMetrics();
int width = metrics.widthPixels;
int height = metrics.heightPixels;

编辑2

试试这段代码：

Dialog yourDialog = dialogFragment.getDialog();
yourDialog.getWindow().setLayout((6 * width)/7, (4 * height)/5);

Answer 2

在自定义布局中设置android：minWidth和android：minHeight对我来说很有用。

Answer 3

<style name="full_screen_dialog" parent="@android:style/Theme.Dialog">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
    <item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:minWidth" type="dimen">600dp</item>
</style>

在style.xml文件中使用此选项，并在对话框类

中使用此样式

Answer 4

在onCreate

中加入以下行

setStyle(DialogFragment.STYLE_NO_TITLE, android.R.style.Theme_Holo_Light_Dialog_NoActionBar_MinWidth);

Answer 5

正确的解决方案是覆盖onCreateDialog方法而不是onCreateView，并使用AlertDialog.Builder创建对话框，如文档中所述：http://developer.android.com/reference/android/app/DialogFragment.html#AlertDialog

Answer 6

对话框的大小取决于其内容。您可以在外部布局上添加填充和边距以消耗更多空间，但这不会重新分配内部视图。

Answer 7

试试这个

根据设备屏幕尺寸设置对话框宽度和高度

    Display display;
    int DisplayWidth, DisplayHeight, DialogWidth, DialogHeight;
    Dialog dialog;

display =((WindowManager)activity_context.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
        DisplayWidth = display.getWidth();
        DisplayHeight = display.getHeight();

        if(DisplayHeight > DisplayWidth)
        {
            DialogWidth = (6 * DisplayWidth) / 7 ;
            DialogHeight = (4 * DisplayHeight) / 5 ;
        }
        else
        {
            DialogWidth = (6 * DisplayWidth) / 9 ;
            DialogHeight = (4 * DisplayHeight) / 5 ;
        }

        dialog = new Dialog(activity_context);

          // Set your dialog width and height dynamically as per your screen.

        Window window = dialog.getWindow();
        window.setLayout(DialogWidth,DialogHeight);
        window.setGravity(Gravity.CENTER);

        dialog.show();

Answer 8

尝试将android:layout_height设置为基本LinearLayout

的某个值

例如

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"

<!-- right here -->
    android:layout_height="100dp"

android:background="@color/white"
android:orientation="vertical" >

Answer 9

将 android：minWidth / android：minHeight 添加到根视图中。见下面的例子：

<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:minWidth="300dp"
android:minHeight="500dp">

Answer 10

我配置了项目，以使DialogFragments的默认对话框主题的宽度最小。

在AndroidManifest.xml中将应用程序的主题设置为您的自定义主题。或者，将托管Activity的{​​{1}}的主题设置为您的应用程序的自定义主题。

DialogFragment

在<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.helloworld"> <application android:name=".App" android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:roundIcon="@mipmap/ic_launcher_round" android:supportsRtl="true" android:theme="@style/AppTheme"> <!-- set the app's theme to your custom theme --> ..... </application> </manifest> 中定义您的自定义主题，并使用您自己定义的主题覆盖用于对话框片段的默认主题。

values/styles.xml

如果您使用深色主题，并且像我在<?xml version="1.0" encoding="utf-8"?> <resources> <style name="AppTheme" parent="Theme.AppCompat"> <!-- override the default theme for DialogFragments --> <item name="android:dialogTheme">@style/AppTheme.Dialog</item> </style> <!-- configure your custom theme for DialogFragments... use a theme that has MinWidth, so that the dialog is not "too small" --> <style name="AppTheme.Dialog" parent="Theme.AppCompat.Dialog.MinWidth"> <!-- override the default theme for DialogFragments spawned by this DialogFragment --> <item name="android:dialogTheme">@style/AppTheme.Dialog</item> <!-- OPTIONAL: override the background for the dialog...i am using a dark theme, and for some reason, there is no themes for dialogs with dark backgrounds, so, i made my own. --> <item name="android:windowBackground">@drawable/dialog__window_background</item> <!-- add the title to the dialog's theme. you can remove it later by using DialogFragment.setStyle() --> <item name="android:windowNoTitle">false</item> <item name="windowNoTitle">?android:windowNoTitle</item> </style> ..... </resources> 中一样覆盖android:windowBackground，则添加一个AppTheme.Dialog文件，其内容如下：

drawable/dialog__window_background.xml

Answer 11

这个技巧对我有用

  override fun onStart() {
        super.onStart()
        val metrics: DisplayMetrics = resources.displayMetrics
        val width: Int = metrics.widthPixels
        dialog?.window?.setLayout(width - 58, 
        ViewGroup.LayoutParams.WRAP_CONTENT)
    }

Answer 12

您可以在下面添加标签

    <Space
            android:layout_width="600dp"
            android:layout_height="1dp"/>

在您的父级布局内部，因此dilog布局会尽可能填充屏幕宽度。

注意android:layout_width="600dp"的值应该大于屏幕显示的值， 我认为600dp对于MobileScreens就足够了。
