我试图改变AlertDialog.Builder的按钮颜色,但我没有找到办法做到这一点。更改AlertDialog.Builder按钮颜色

我想要改变按钮的颜色和标题为白色,就像在HOLO主题。

看到这些2个截图例子:

伊夫看着这里:

How to change theme for AlertDialog

Change the style of AlertDialog

How to change the background of the custom alert dialog

Applying Styles Android

所有这些都没有为我工作。

这里是我的代码:

public void logInDialog() 
{ 
    ContextThemeWrapper ctw = new ContextThemeWrapper(this, R.style.dialogStyle); 
    AlertDialog.Builder builder = new AlertDialog.Builder(ctw); 
    builder.setTitle("Log in"); 
    View prefView = View.inflate(this, R.layout.log_in, null); 
    //The rest of the code......... 
} 

这是我的风格代码:

<?xml version="1.0" encoding="utf-8"?> 
<resources> 
    <style name="dialogStyle" parent="android:Theme.Dialog"> 
     <item name="android:background">@color/white</item> 
     <item name="android:layout_width">wrap_content</item> 
     <item name="android:layout_height">wrap_content</item> 
     <item name="android:button">@color/white</item> 
    </style>  
</resources>

我知道这是一个非常古老的问题,但我同样的问题遇到了,我发现一个解。 为了改变文本的颜色的警报对话框的按钮内,你应该做这样的事情:

public void logInDialog() 
{ 
    AlertDialog.Builder builder = new AlertDialog.Builder(context); 
    LayoutInflater inflater = context.getLayoutInflater(); 

    //setting custom view for our dialog 
    View myview = inflater.inflate(R.layout.YOUR_CUSTOM_LAYOUT, null); 
    builder.setNeutralButton(android.R.string.cancel, null); 
    builder.setView(myview); 

    //creating an alert dialog from our builder. 
    AlertDialog dialog = builder.create(); 
    dialog.show(); 

    //retrieving the button view in order to handle it. 
    Button neutral_button = dialog.getButton(DialogInterface.BUTTON_NEUTRAL); 

    Button positive_button = dialog.getButton(DialogInterface.BUTTON_POSITIVE); 


    if (neutral_button != null) { 
     neutral_button.setBackgroundDrawable(context.getResources() 
         .getDrawable(R.drawable.custom_background)); 

     neutral_button.setTextColor(context.getResources() 
         .getColor(android.R.color.white)); 
    } 
    if (positive_button != null) { 
     positive_button.setBackgroundDrawable(context.getResources() 
         .getDrawable(R.drawable.custom_background)); 

     positive_button.setTextColor(context.getResources() 
         .getColor(android.R.color.white)); 
    } 

} 

而且按钮所处的个XML使用:

custom_background.xml

<layer-list xmlns:android="http://schemas.android.com/apk/res/android" > 

    <item android:drawable="#000000"/> 
    <item android:drawable="@drawable/selectable_item_background"/> 

</layer-list> 

而且selectable_item_background.xml:

<selector xmlns:android="http://schemas.android.com/apk/res/android"> 

    <item android:drawable="@drawable/item_pressed" android:state_pressed="true"/> 
    <item android:drawable="@drawable/item_focused" android:state_focused="true"/> 
    <item android:drawable="@drawable/item_focused" android:state_selected="true"/> 
    <item android:drawable="@android:color/transparent"/> 

</selector> 

我个人在片段内使用了这段代码,这就是为什么我有一个LayoutInflater。在你的情况下,你可以跳过这一步。 希望它能帮助未来的其他人。

更改AlertDialog的按钮颜色。

// Initialize AlertDialog & AlertDialog Builder 
AlertDialog.Builder builder = new AlertDialog.Builder(YourActivity.this); 
builder.setTitle(R.String.AlertDialogTitle); 
........... 
......... 
//Build your AlertDialog 
AlertDialog Demo_alertDialog= builder.create(); 
Demo_alertDialog.show(); 

//For Positive Button: 
Button b_pos; 
b_pos=Demo_alertDialog.getButton(DialogInterface.BUTTON_POSITIVE); 
if(b_pos!=null){ 
    b_pos.setTextColor(getResources().getColor(R.color.YourColor)); 
    }  


//For Neutral Button: 
Button b_neu; 
b_neu=Demo_alertDialog.getButton(DialogInterface.BUTTON_NEUTRAL); 
if(b_neu!=null){ 
    b_neu.setTextColor(getResources().getColor(R.color.YourColor)); 
    } 

//For Negative Button: 
Button b_neg; 
b_neg=Demo_alertDialog.getButton(DialogInterface.BUTTON_NEGATIVE); 
if(b_neg!=null){ 
    b_neg.setTextColor(getResources().getColor(R.color.YourColor)); 
    } 

编码快乐:)

为了跟进@ Ioumaros的回答,setBackgroundDrawable现在已经过时。您可以使用此代码实现相同的背景颜色变化:

Button negativeButton = alertDialog.getButton(DialogInterface.BUTTON_NEGATIVE); 
    negativeButton.setBackgroundColor(getResources().getColor(R.color.colorBackground)); 

    Button positiveButton = alertDialog.getButton(DialogInterface.BUTTON_POSITIVE); 
    positiveButton.setBackgroundColor(getResources().getColor(R.color.colorBackground)); 

但是编程这样做是不是通常认为的最佳方式......
