Answer 1

我還沒有嘗試修改默認Toast，但可以爲Toast創建自定義佈局，然後在佈局文件中設置android：alpha。

靜態調用，這樣就可以從任何地方調用它：

public static void showDialog(Context context, String text) 
{ 

    LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

    View toastLayout = inflater.inflate(R.layout.toast_custom, null); 

    // Notify the user 
    TextView textView = (TextView) toastLayout.findViewById(R.id.text); 
    textView.setText(text);    
    Toast toast = new Toast(context); 
    toast.setDuration(1000); 
    toast.setGravity(Gravity.CENTER, 0, 0); 
    toast.setView(toastLayout); 
    toast.show();    

} 

佈局文件toast_custom.xml：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/toast_layout_root" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:orientation="horizontal" 
android:padding="20dp"  
android:alpha="0.5" 
>  

<TextView   
    android:id="@+id/text" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_gravity="center" 
    android:textColor="#000" 
    android:textSize="24sp" 
    android:textStyle="bold"   
    />
