AlertDialog僅在Android上顯示中性按鈕<7.0

我製作了一個AlertDialog，它有三個按鈕（正面，負面，中性），當我在手機上測試時它工作正常（Android 7.0），但我有幾個朋友與Android 5.0和6.0）測試它們，他們只有中性按鈕顯示。AlertDialog僅在Android上顯示中性按鈕<7.0

下面是代碼：

AlertDialog.Builder isSelfieBuilder = new AlertDialog.Builder(context); 
isSelfieBuilder.setTitle("Choose picture orientation."); 

// Set up the buttons 
isSelfieBuilder.setPositiveButton("Selfie", new DialogInterface.OnClickListener() { 
    @Override 
    public void onClick(DialogInterface dialog, int which) { 
     //Do something 
    } 
}); 
isSelfieBuilder.setNeutralButton("Landscape", new DialogInterface.OnClickListener() { 
    @Override 
    public void onClick(DialogInterface dialog, int which) { 
     //Do something 
    } 
}); 
isSelfieBuilder.setNegativeButton("Portrait", new DialogInterface.OnClickListener() { 
    @Override 
    public void onClick(DialogInterface dialog, int which) { 
     //Do something 
    } 
}); 
final AlertDialog picTypeDialog = isSelfieBuilder.create(); 
picTypeDialog.show(); 

final Button positiveButton = picTypeDialog.getButton(AlertDialog.BUTTON_POSITIVE); 
LinearLayout.LayoutParams positiveButtonLL = (LinearLayout.LayoutParams) positiveButton.getLayoutParams(); 
positiveButtonLL.width = ViewGroup.LayoutParams.MATCH_PARENT; 
positiveButton.setLayoutParams(positiveButtonLL); 

final Button neutralButton = picTypeDialog.getButton(AlertDialog.BUTTON_NEUTRAL); 
LinearLayout.LayoutParams neutralButtonLL = (LinearLayout.LayoutParams) neutralButton.getLayoutParams(); 
neutralButtonLL.width = ViewGroup.LayoutParams.MATCH_PARENT; 
neutralButton.setLayoutParams(neutralButtonLL); 

final Button negativeButton = picTypeDialog.getButton(AlertDialog.BUTTON_NEGATIVE); 
LinearLayout.LayoutParams negativeButtonLL = (LinearLayout.LayoutParams) negativeButton.getLayoutParams(); 
negativeButtonLL.width = ViewGroup.LayoutParams.MATCH_PARENT; 
negativeButton.setLayoutParams(negativeButtonLL);

任何人有任何想法，爲什麼我只在那裏得到的中性按鈕？我嘗試刪除對齊部分（.show()後的所有內容），但我得到了相同的結果。我正在使用API 21（5.0）的模擬器上測試，並且遇到同樣的問題。

確定它必須使用android版本做些什麼？也許更多的屏幕尺寸導致它.... – Opiatefuchs

final AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); 
     builder.setTitle("Choose picture orientation.") 
       .setPositiveButton("Selfie", new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog, int id) { 
         //doSomething 
        } 
       }) 
       .setNeutralButton("Landscape", new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog, int id) { 
         //doSomething 
        } 
       }) 
       .setNegativeButton("Portrait", new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog, int id) { 
         //doSomething 
        } 
       }); 
     AlertDialog dialog = builder.create(); 
     dialog.show();

所以我的「固定」的方式，這是通過完全禁用：

AlertDialog picTypeDialog = isSelfieBuilder.create(); 
picTypeDialog.show();

而且隨着

isSelfieBuilder.show();

現在適用於所有設備優良，即使間距簡單地更換它之間的按鈕是不完美的，我不能編輯按鈕佈局沒有AlertDialog。
