我有一個嘗試創建自定義Toast對象的活動。我希望烤麪包出現在屏幕的中央,但無論我設定的重力是什麼,烤麪包都會出現在頂部。看起來我給敬酒的設置對發生的事情沒有影響。我能做些什麼來將敬酒移到中心。爲什麼SetGravity onToast沒有效果?
的代碼來創建敬酒:
LayoutInflater inflater = (LayoutInflater) context.getSystemService
(Context.LAYOUT_INFLATER_SERVICE);
RelativeLayout layout = (RelativeLayout) inflater.inflate(R.layout.notification_layout,null);
((TextView) layout.findViewById(R.id.title)).setText(title);
((TextView) layout.findViewById(R.id.content)).setText(content);
Toast toast = new Toast(this);
toast.setDuration(Toast.LENGTH_SHORT);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.setView(layout);
toast.show();
的佈局膨脹的XML:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="100dp"
android:id="@+id/notificationToast">
<ImageView
android:layout_width="50dp"
android:layout_height="50dp"
android:src="@drawable/ic_launcher"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true"
android:id="@+id/imageView4" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Title"
android:id="@+id/title"
android:gravity="center"
android:layout_alignBottom="@+id/imageView4"
android:layout_alignParentTop="true"
android:layout_alignParentEnd="true"
android:layout_toEndOf="@+id/imageView4" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="content"
android:id="@+id/content"
android:layout_below="@+id/imageView4"
android:layout_alignParentStart="true"
android:layout_alignParentBottom="true"
android:layout_alignParentEnd="true" />
</RelativeLayout>
愚蠢的小失誤總是最長的發現。謝謝 – nbroeking
