E/WindowManager: android.view.WindowLeaked: Activity com.activity.LoginActivity has leaked window DecorView@9a11182[] that was originally added here

看提示是窗口泄露。

错误原因是因为activity中的Dialog、PopupWindow不能脱离activity而单独存在。当Dialog、PopupWindow正在显示的时候而它们依附的activity却destroy了，就会出现WindowLeaked异常。

解决办法是在finish 某个activity之前要确保依附于其上的Dialog、PopupWindow已经dismiss了

@Override
    protected void onDestroy() {
        super.onDestroy();
        if(progressDialog!=null&&progressDialog.isShowing()) {
            progressDialog.dismiss();
        }
    }

也可在OnCreateDialog()中创建Dialog，让系统去管理对话框。
