PopupWindow的基本使用

1>写好布局

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="wrap_content"

    android:layout_height="wrap_content"

    android:background="@color/colorPrimary"

    android:orientation="vertical" >

    <LinearLayout

        android:id="@+id/edit_alarm"

        android:layout_width="match_parent"

        android:layout_height="60dp">

        <ImageView

            android:layout_width="24dp"

            android:layout_marginLeft="16dp"

            android:layout_height="match_parent"

            android:src="@drawable/ic_alarm_add"/>

        <TextView

            android:layout_width="match_parent"

            android:layout_height="match_parent"

            android:text="@string/edit_alarm"

            style="@style/popupwindow_text_style"/>

    </LinearLayout>

    <View

        android:layout_width="220dp"

        android:layout_height="1dp"

        android:background="?android:attr/listDivider" />

    <LinearLayout

        android:id="@+id/clear_alarm"

        android:layout_width="match_parent"

        android:layout_height="60dp"

        >

        <ImageView

            android:layout_width="24dp"

            android:layout_height="match_parent"

            android:layout_marginLeft="16dp"

            android:src="@drawable/ic_alarm_off"/>

        <TextView

            android:layout_width="match_parent"

            android:layout_height="wrap_content"

            style="@style/popupwindow_text_style"

            android:text="@string/clear_alarm" />

    </LinearLayout>

</LinearLayout>

2>代码：

public void showAlarmPopupWindow() {

        View view = LayoutInflater.from(getContext()).inflate(R.layout.alarm_popupwindow , null ,false);

        LinearLayout editLayout = (LinearLayout)view.findViewById(R.id.edit_alarm);

        LinearLayout clearLayout = (LinearLayout)view.findViewById(R.id.clear_alarm);

        final PopupWindow popupWindow = new PopupWindow(view , ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT , true);

        editLayout.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View view) {

                popupWindow.dismiss();

                mPresenter.editAlarm();

            }

        });

        clearLayout.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View view) {

                popupWindow.dismiss();

                mPresenter.clearAlarm();

            }

        });

        popupWindow.setAnimationStyle(android.R.style.Animation_Dialog);

        popupWindow.showAsDropDown(getActivity().findViewById(R.id.toolbar) , getActivity().getWindowManager().getDefaultDisplay().getWidth() - popupWindow.getWidth() , 1);

    }
