我可以在Android中使用什么而不是上下文菜单?[英] What can I use instead of Context Menu in android?

问题描述

I want to show some options when clicking a button. I use context menu now. But the context menu showing below Android 3 is not good with the current app design. I want to either change the style of the context menu or use some other controls or replace the context menu with something else. What can I do to make my app design more beautiful? Is there any material design library with material context menu?

推荐答案

You can use the PopupWindow which starts from API level 1.

In PopupWindow you can actually design something with XML Layout file. You can include anything (TextView,Button,ImageView,...) Like : PopUp Window XML :

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="15dp"
    android:background="#89000000"
    android:orientation="vertical">


    <Button
        android:id="@+id/idClose"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Close"
        android:layout_below="@+id/textView4"
        android:layout_alignRight="@+id/textView4"
        android:layout_alignEnd="@+id/textView4" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="PopUp Window Title"
        android:id="@+id/textView"
        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:textStyle="bold" />

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="Item One / Option One"
        android:id="@+id/textView2"
        android:layout_below="@+id/textView"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="10dp"
        android:gravity="center" />

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="Item Two / Option Two"
        android:id="@+id/textView3"
        android:layout_below="@+id/textView2"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="5dp"
        android:gravity="center" />

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="..."
        android:id="@+id/textView4"
        android:layout_below="@+id/textView3"
        android:layout_centerHorizontal="true"
        android:gravity="center"
        android:layout_marginTop="5dp" />

</RelativeLayout>

Main Activity XML :

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <Button
        android:id="@+id/idOpen"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Open"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true" />

</RelativeLayout>

And you can Pop It Up in Activity like :

package com.example.popup;

import android.app.Activity;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.WindowManager;
import android.widget.Button;
import android.widget.PopupWindow;


public class MainActivity extends Activity {

    Button open;
    LayoutInflater inflater;
    View popUpView;
    PopupWindow popupWindow;
    Button close;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        open = (Button)findViewById(R.id.idOpen);
        open.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                popupWindow.showAsDropDown(open);
            }
        });

        inflater =(LayoutInflater) getBaseContext().getSystemService(LAYOUT_INFLATER_SERVICE);
        popUpView = inflater.inflate(R.layout.popup_window,null);
        popupWindow = new PopupWindow(popUpView, WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.WRAP_CONTENT);
        close = (Button)popUpView.findViewById(R.id.idClose);
        close.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                popupWindow.dismiss();
            }
        });


    }
}

HOPE THIS WILL HELP, HAPPY CODING :)
