我将代码从Eclipse迁移到Android Studio。我收到以下错误
java.lang.ClassCastException: android.widget.FrameLayout$LayoutParams cannot be cast to android.view.WindowManager$LayoutParams
。但是代码在Eclipse中完美运行，但在android studio中却没有。我无法找出问题所在。
我的代码是。
private void popup_otp() {
// TODO Auto-generated method stub
View popupView = LoginActivity.this.getLayoutInflater()
.inflate(R.layout.pop_up_otp, null);
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
int height = metrics.heightPixels;
int width = metrics.widthPixels;
/*
* int h = height; double a= width /4;
*/
int wwidth = width / 6;
int w = width - wwidth;
final PopupWindow popupWindow = new PopupWindow(popupView, w,
LayoutParams.WRAP_CONTENT);
popupWindow.setFocusable(true);
popupWindow.setBackgroundDrawable(new BitmapDrawable(
getResources(), ""));
//popupWindow.showAtLocation(v, Gravity.CENTER, 0, 0);
// If you need the PopupWindow to dismiss when when touched
// outside
// popupWindow.setBackgroundDrawable(new ColorDrawable());
ColorDrawable dw = new ColorDrawable(0xb0000000);
popupWindow.setBackgroundDrawable(dw);
int location[] = new int[2];
// Get the View's(the one that was clicked in the Fragment)
// location
popupView.getLocationOnScreen(location);
// Using location, the PopupWindow will be displayed right under
// anchorView
popupWindow.showAtLocation(popupView, Gravity.CENTER, 0, 0);
View container = (View) popupWindow.getContentView().getParent();
WindowManager wm = (WindowManager) getSystemService(Context.WINDOW_SERVICE);
WindowManager.LayoutParams p = (WindowManager.LayoutParams) container
.getLayoutParams();
p.flags = WindowManager.LayoutParams.FLAG_DIM_BEHIND;
p.dimAmount = 0.8f;
wm.updateViewLayout(container, p);
TextView ok_submit_txtView=(TextView)popupView.findViewById(R.id.ok_submit_txtView);
WebView webview=(WebView)popupView.findViewById(R.id.web_view_item);
String data="Dear user, you have not completed the OTP verification yet.You will be now redirected to the OTP screen and your OTP will be resent to you.";
String text = "<html><body>"
+ "<p align=\"justify\">"
+ data
+ "</p> "
+ "</body></html>";
webview.loadData(text, "text/html", "utf-8");
ok_submit_txtView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
popupWindow.dismiss();
Intent intent = new Intent(LoginActivity.this, OTPActivity.class);
intent.putExtra("OTP", OTP);
intent.putExtra("checking", 22);
startActivity(intent);
System.out.println("otp" + OTP + responce_message);
}
});
}
xml是
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FFFFFF"

<WebView

</LinearLayout>
