所以我制作了一个简单的应用程序,你点击一个按钮,它会显示一个带有按钮随机字符串的弹出窗口。
问题是,当创建弹出窗口时,它是一个小盒子。像100x100或其他东西。这是弹出代码。你可以看到我尝试设置550和750,作为大小,如果我把70和550,它将完美地工作,并且是非常小的宽度,并且长期明智地伸展。但是在100dp之后,它会回到正方形
public void showPopup(View v){
View popupView = getLayoutInflater().inflate(R.layout.popup_layout, null);
PopupWindow popupWindow = new PopupWindow(popupView, 550, 750);
// Example: If you have a TextView inside `popup_layout.xml`
TextView tv = (TextView) popupView.findViewById(R.id.tv);
String[] myString;
Resources res = getResources();
myString = res.getStringArray(R.array.myArray);
String q = myString[rgenerator.nextInt(myString.length)];
tv.setText(q);
// Initialize more widgets from `popup_layout.xml`
// If the PopupWindow should be focusable
popupWindow.setFocusable(true);
// If you need the PopupWindow to dismiss when when touched outside
popupWindow.setBackgroundDrawable(new ColorDrawable());
// Get the View's(the one that was clicked in the Fragment) location
//v.getLocationOnScreen(location);
// Using location, the PopupWindow will be displayed right under anchorView
popupWindow.showAtLocation(v, Gravity.CENTER, 0, 0);
}
这是我的弹出式布局
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:background="@drawable/blank">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:id="@+id/tv"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:textColor="#FFFF"
android:layout_gravity="center" />
</FrameLayout>
答案 0 :(得分:0)
android:layout_width="wrap_content" android:layout_height="wrap_content"
尝试使用match_parent
