我已經爲這個問題建立了很多解決方案,但是他們都沒有爲我工作。我想在片段中顯示一個PopupWindow。這是我的代碼PopupWindow沒有顯示
LayoutInflater layoutInflater = LayoutInflater.from(getActivity());
View popupView = layoutInflater.inflate(R.layout.pop_up_cargando, null,false);
this.popupWindow = new PopupWindow(popupView, popupView.getWidth(),popupView.getHeight());
this.popupWindow.setFocusable(true);
int location[] = new int[2];
this.btnInventario.getLocationOnScreen(location);
this.popupWindow.showAtLocation(this.btnInventario, Gravity.NO_GRAVITY, location[0], location[1] + btnInventario.getHeight()); // this.btnInventario is the button that calls this code
this.popupWindow.update(0, 0, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
但是PopupWindow從不出現。
編輯:這是pop_up_cargando
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/popup_recomendar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ffffff"
android:orientation="vertical" >
<ProgressBar
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="180dp"
android:layout_height="wrap_content"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:layout_marginTop="20dp"
android:layout_gravity="center"
android:id="@+id/cargando"/>
<TextView
android:id="@+id/txtTexto"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="20dp"
android:layout_marginBottom="20dp"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:layout_gravity="center"
android:text="@string/vacio"
android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>
任何建議的內容?我做錯了什麼?您的幫助將非常感激。
我使用的是popupWindow.showAtLocation。它在代碼 – martinc 2014-10-02 16:31:14
檢查'popupView.getWidth()'和'popupView.getHeight()'值是否大於0. – 2014-10-02 16:59:51
@ G.T。兩者都是0 ...沒有注意到。我該如何解決它? – martinc 2014-10-02 17:12:31
