添加Menu文件

在这里插入图片描述

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

处理menu的点击事件

package com.example.materialdesign;

import androidx.appcompat.app.AppCompatActivity;
import androidx.appcompat.widget.Toolbar;

import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {
    
    
    private Toolbar toolbar;

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

        toolbar = findViewById(R.id.toolbar);

        toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
    
    
            @Override
            public boolean onMenuItemClick(MenuItem item) {
    
    
                int itemId = item.getItemId();
                if(itemId == R.id.bar_add){
    
    
                    Toast.makeText(MainActivity.this, "添加按钮", Toast.LENGTH_SHORT).show();
                }
                return false;
            }
        });
    }

}

CardView

                android:text="我是CradView中的文本" />

        </LinearLayout>
    </androidx.cardview.widget.CardView>

</LinearLayout>

在这里插入图片描述

为CardView添加点击涟漪效果

android:foreground="?android:attr/selectableItemBackground"

沉浸式标题栏

第一种方式直接设置状态栏颜色使状态栏颜色和标题栏相同或相近

getWindow().setStatusBarColor(Color.RED);

第二种方式将状态栏设置为透明标题栏留出上边距
① 添加透明标题栏的样式

   <style name="TranslucentTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="android:windowTranslucentStatus">true</item>
        <item name="android:windowTranslucentNavigation">false</item>
        <!--Android 5.x开始需要把颜色设置透明，否则导航栏会呈现系统默认的浅灰色-->
        <item name="android:statusBarColor">@android:color/transparent</item>
    </style>

②设置activity的样式

 <activity android:name=".MainActivity"
            android:theme="@style/TranslucentTheme">

参考网址 Android Material Design系列之FloatingActionButton和Snackbar

FloatingActionButton

<com.google.android.material.floatingactionbutton.FloatingActionButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/fb"
        android:layout_alignParentRight="true"
        android:layout_alignParentBottom="true"
        android:layout_margin="35dp"
        android:src="@mipmap/ic_launcher"
        android:scaleType="centerCrop"
        app:elevation="8dp"/>

Snackbar

点击fab弹出Snackbar

 fab = findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
    
    
            @Override
            public void onClick(View v) {
    
    
                Toast.makeText(MainActivity.this,
                        "按钮被点击了",Toast.LENGTH_SHORT).show();

                Snackbar.make(fab, "清明节要放假啦", Snackbar.LENGTH_SHORT)
                        .setAction("确定", new View.OnClickListener() {
    
    
                            @Override
                            public void onClick(View v) {
    
    
                                Toast.makeText(MainActivity.this,
                                        "我要回家了",Toast.LENGTH_SHORT).show();
                            }
                        })
                        .show();
            }
        });

BottomSheet

底部弹窗:BottomSheetBehavior使用

        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <com.google.android.material.floatingactionbutton.FloatingActionButton

        app:behavior_peekHeight="20dp"

                android:text="我是BottomSheet的文本" />
        </LinearLayout>
    </LinearLayout>


</androidx.coordinatorlayout.widget.CoordinatorLayout>

用Fab按钮控制底部的弹出和隐藏

 llBottom = findViewById(R.id.ll_bottom);

        fab = findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
    
    
            @Override
            public void onClick(View v) {
    
    

                BottomSheetBehavior behavior = BottomSheetBehavior.from(llBottom);
                if(behavior.getState() == BottomSheetBehavior.STATE_COLLAPSED){
    
    
                    behavior.setState(BottomSheetBehavior.STATE_EXPANDED);
                }else {
    
    
                    behavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
                }
            }
        });

在这里插入图片描述
需要创建一个sheet_dialog.xml布局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"

        android:id="@+id/ll_bottom"
        android:layout_width="match_parent"
        android:layout_height="100dp"
        android:background="#3300FF00"
        app:behavior_hideable="true"
        app:behavior_peekHeight="20dp"
        app:layout_behavior="com.google.android.material.bottomsheet.BottomSheetBehavior"
        >

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="100dp"
            android:orientation="vertical">

            <TextView
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:text="我是BottomSheet的文本" />
        </LinearLayout>
</LinearLayout>

点击按钮弹出对话框

 fab = findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
    
    
            @Override
            public void onClick(View v) {
    
    
                BottomSheetDialog dialog = new BottomSheetDialog(MainActivity.this);
                dialog.setContentView(R.layout.sheet_dialog);
                dialog.show();
            }
        });
