問題描述

我正在嘗試在 Android 中創建自定義對話框.但是無論我嘗試做什么，我都無法更改對話框的寬度.它只是保持不變.以下是我設置為對話框內容的視圖.

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>

如您所見，我在此代碼示例中使用 wrap_content 的所有地方.我也嘗試了以下選項

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

1) 像這樣創建對話框時設置自定義樣式.

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

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

并且樣式如下

<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) 像這樣在 onCreateDialog() 中設置視圖的參數

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) 我也嘗試在 onCreateDialog() 方法中設置這樣的 Window 參數

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);

但還是沒有運氣.有人可以幫我解決這個問題.難道我做錯了什么??您能否建議我如何設置對話框窗口的 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?

謝謝

推薦答案

找了好久才發現問題.問題在于我使用相對布局的方式.我想我沒有正確指定相對位置.當我將其更改為線性布局時，它工作正常.它并沒有用完整個屏幕，而是只用了需要的東西.

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.
