如何更改ProgressDialog的外觀？

Question

我知道this is possible，但我想知道爲什麼我的解決方案無法正常工作。

ProgressDialog dialog = new ProgressDialog(context); 
dialog.setProgressStyle(ProgressDialog.STYLE_SPINNER); 
dialog.setIndeterminate(true); 
dialog.setCancelable(false); 
dialog.setCanceledOnTouchOutside(false); 
TextView textView = (TextView) LayoutInflater.from(context).inflate(R.layout.custom_text, null, false); 
textView.setText(context.getResources().getString(msg)); 
dialog.setView(textView); 

這是custom_text

<?xml version="1.0" encoding="utf-8"?> 
<TextView xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/messageSpinner" 
style="@style/TextAppearance.AppCompat.Medium" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:textColor="@color/colorAccent" 
android:textStyle="bold"> 

</TextView> 

佈局的結果是與期望的葉輪，但空消息的窗口。

Answer 1

您正在重寫對話框視圖。現在對話框只顯示您的自定義視圖。嘗試添加進度條也佈局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent"> 
<ProgressBar 
android:layout_width="30dp" 
android:layout_height="30dp"/> 


<TextView xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/messageSpinner" 
style="@style/TextAppearance.AppCompat.Medium" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:textColor="@color/colorAccent" 
android:textStyle="bold"> 

</TextView> 
</LinearLayout>
