在 Android 中创建自定义对话框

Creating a custom dialog in Android(在 Android 中创建自定义对话框)

问题描述

我正在尝试在 Android 中创建自定义对话框.但是无论我尝试做什么，我都无法更改对话框的宽度.它只是保持不变.以下是我设置为对话框内容的视图.

I am trying to create a custom dialog in Android. But whatever I tried to do, I am not able to change the width of the dialog. It just remains the same. The following is the view that I am setting as the content for the dialog.

<RelativeLayout  
android:id="@+id/current_stats"
android:layout_width="wrap_content"
android:layout_height="wrap_content" 
android:visibility="visible">
<ImageView android:id="@+id/player_image" 
    android:src="@drawable/person"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"/>
<TextView   
    android:id="@+id/player_name"
    android:layout_below="@id/player_image"
    android:layout_centerHorizontal="true"
    android:text="Raja Ram"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"/>
<ImageButton android:id="@+id/dialog_close"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_alignParentRight="true"
    android:background="#00000000"
    android:src="@drawable/close_button_selector"/>
<ImageButton android:id="@+id/dialog_flip"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_alignParentLeft="true"
    android:background="#00000000"
    android:src="@drawable/rotate"/>
</RelativeLayout>

如您所见，我在此代码示例中使用 wrap_content 的所有地方.我也尝试了以下选项

As you can see, everywhere I am using wrap_content in this code sample. Also I tried the following options

1) 像这样创建对话框时设置自定义样式.

1) Setting a custom style while creating the Dialog like this.

dialog = new Dialog(this,R.style.Theme_Dialog);

并且样式如下

<resources>
<style name="Theme" parent="android:Theme">
</style>
<style name="Theme.Dialog">
    <item name="android:layout_width">wrap_content</item>
    <item name="android:layout_height">wrap_content</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>
</style>
</resources>

2) 像这样在 onCreateDialog() 中设置视图的参数

2) Setting the parameters for the view in the onCreateDialog() like this

LayoutInflater inflater = (LayoutInflater)this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = inflater.inflate(R.layout.player_info, null, false);
ViewGroup.LayoutParams p = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT,ViewGroup.LayoutParams.WRAP_CONTENT);
dialog.setContentView(v,p);

3) 我也尝试在 onCreateDialog() 方法中设置这样的 Window 参数

3) I also tried to set the Window parameters like this in the onCreateDialog() method

WindowManager.LayoutParams params = dialog.getWindow().getAttributes();
params.width=WindowManager.LayoutParams.WRAP_CONTENT;
dialog.getWindow().setAttributes(params);

但还是没有运气.有人可以帮我解决这个问题.难道我做错了什么??您能否建议我如何设置对话框窗口的 x 和 y 位置?

But again no luck. Can someone help me out with this issue. Am I doing something wrong?? Also can you please suggest me how to set the x and y postions for the Dialog window?

谢谢

推荐答案

找了好久才发现问题.问题在于我使用相对布局的方式.我想我没有正确指定相对位置.当我将其更改为线性布局时，它工作正常.它并没有用完整个屏幕，而是只用了需要的东西.

I figured out the problem after a long time. The problem was with the way I used Relative layout. I guess I have not specified the relative position properly. When I changed that to linear layout it worked fine. It was not using up the whole screen but only whatever is required.
