在對話框中不顯示Android平面按鈕

Question

我一直在設計一個對話框來評價我的遊戲。我設計了看起來像這樣一個XML文件 -

Rate App XML Design

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:background="#F5F5F5"> 

<LinearLayout 
    android:id="@+id/LL1" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:layout_marginBottom="8dp" 
    android:layout_marginLeft="24dp" 
    android:layout_marginRight="24dp" 
    android:layout_marginTop="24dp"> 

    <ImageView 
     android:id="@+id/image" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_marginRight="10dp" /> 

    <TextView 
     android:id="@+id/text" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 

     android:layout_marginTop="10dp" 
     android:text="Rate My game" 
     android:textColor="#000000" 
     android:textSize="24sp" /> 

</LinearLayout> 

<View 
    android:id="@+id/singleLine" 
    android:layout_width="fill_parent" 
    android:layout_height="2dp" 
    android:layout_below="@id/LL1" 
    android:layout_marginBottom="8dp" 
    android:background="#2196F3" /> 


<TextView 
    android:id="@+id/Description_text" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:layout_below="@id/singleLine" 
    android:layout_marginBottom="24dp" 
    android:layout_marginLeft="24dp" 
    android:layout_marginRight="24dp" 
    android:layout_marginTop="12dp" 
    android:text="If you enjoy Playing My Game take a moment to rate 
    it. Thanks for your Support!" 
    android:textColor="#000000" 
    android:textSize="16sp" /> 


<LinearLayout 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:layout_below="@id/Description_text" 

    android:layout_margin="8dp"> 

    <Button 
     android:id="@+id/rate_button" 
     style="?android:attr/borderlessButtonStyle" 
     android:layout_width="0dp" 
     android:layout_height="wrap_content" 
     android:layout_weight="2" 
     android:text="RATE" 
     android:textAllCaps="true" 
     android:textColor="#424242" 
     android:textSize="14sp" 

     /> 

    <Button 
     android:id="@+id/remind_me_later_button" 
     style="?android:attr/borderlessButtonStyle" 
     android:layout_width="0dp" 
     android:layout_height="wrap_content" 

     android:layout_weight="4" 
     android:text="REMIND ME LATER" 
     android:textAllCaps="true" 
     android:textColor="#424242" 
     android:textSize="14sp" 

     /> 

    <Button 
     android:id="@+id/never_button" 
     style="?android:attr/borderlessButtonStyle" 
     android:layout_width="0dp" 
     android:layout_height="wrap_content" 

     android:layout_weight="2" 
     android:text="NEVER" 
     android:textAllCaps="true" 
     android:textColor="#424242" 
     android:textSize="14sp" 

     /> 


</LinearLayout> 

但是當使用它作爲對話的扁平按鈕莫名其妙地轉換爲普通按鈕像這個 -

Flat button in XML

用於顯示它的Java代碼 -

public class AppRater extends AppCompatActivity { 
private final static String APP_TITLE = "My Game"; 
private final static String APP_PNAME = "com.alala.blabla"; 

private final static int DAYS_UNTIL_PROMPT = 0; 
private final static int LAUNCHES_UNTIL_PROMPT = 1; 

public static void app_launched(Context mContext) { 
    SharedPreferences prefs = mContext.getSharedPreferences("apprater", 0); 
    if (prefs.getBoolean("dontshowagain", false)) { 
     return; 
    } 

    SharedPreferences.Editor editor = prefs.edit(); 

    // Increment launch counter 
    long launch_count = prefs.getLong("launch_count", 0) + 1; 
    editor.putLong("launch_count", launch_count); 

    // Get date of first launch 
    Long date_firstLaunch = prefs.getLong("date_firstlaunch", 0); 
    if (date_firstLaunch == 0) { 
     date_firstLaunch = System.currentTimeMillis(); 
     editor.putLong("date_firstlaunch", date_firstLaunch); 
    } 

    // Wait at least n days before opening 
    if (launch_count >= LAUNCHES_UNTIL_PROMPT) { 
     if (System.currentTimeMillis() >= date_firstLaunch + 
       (DAYS_UNTIL_PROMPT * 24 * 60 * 60 * 1000)) { 
      showRateDialog(mContext, editor); 
     } 
    } 

    editor.commit(); 
} 

public static void showRateDialog(final Context mContext, 
final SharedPreferences.Editor editor) { 


    final Dialog dialog = new Dialog(mContext, R.style.FullHeightDialog); 
    dialog.setContentView(R.layout.customapprater); 
    Button b1 = (Button) dialog.findViewById(R.id.rate_button); 
    b1.setOnClickListener(new OnClickListener() { 
     public void onClick(View v) { 
      if (editor != null) { 
       editor.putBoolean("dontshowagain", true); 
       editor.commit(); 
      } 
      mContext.startActivity(new Intent(
Intent.ACTION_VIEW,  Uri.parse("market://details?id=" + APP_PNAME))); 
      dialog.dismiss(); 
     } 
    }); 


    Button b2 = (Button) dialog.findViewById(R.id.remind_me_later_button); 
    b2.setOnClickListener(new OnClickListener() { 
     public void onClick(View v) { 
      if (editor != null) { 
       editor.clear().commit(); 
      } 
      dialog.dismiss(); 
     } 
    }); 


    Button b3 = (Button) dialog.findViewById(R.id.never_button); 

    b3.setOnClickListener(new OnClickListener() { 
     public void onClick(View v) { 
      if (editor != null) { 
       editor.putBoolean("dontshowagain", true); 
       editor.commit(); 
      } 
      dialog.dismiss(); 
     } 
    }); 
    dialog.show(); 
} 
} 

我做錯了什麼？

請將您的對話框更改爲AlertDialog。你可以閱讀關於他們here。

public static void showRateDialog(final Context mContext, final SharedPreferences.Editor editor) { 
    new AlertDialog.Builder(mContext) 
      .setTitle(R.string.rate_dialog_title) 
      .setMessage(R.string.rate_dialog_message) 
      .setPositiveButton(R.string.rate, new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface dialog, int which) { 
        if (editor != null) { 
         editor.putBoolean("dontshowagain", true); 
         editor.commit(); 
        } 

        mContext.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + APP_PNAME))); 
       } 
      }) 
      .setNegativeButton(R.string.never, new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface dialog, int which) { 
        if (editor != null) { 
         editor.putBoolean("dontshowagain", true); 
         editor.commit(); 
        } 
       } 
      }) 
      .setNeutralButton(R.string.remind_later, new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface dialog, int which) { 
        if (editor != null) { 
         editor.clear().commit(); 
        } 
       } 
      }) 
      .show(); 
}
