Android: 切换按钮是否有按钮点击动画？

Question

我想在您单击切换按钮上的按钮时复制相同的动画。比如从中间变成灰色的区域用深灰色的圆圈等

目前，切换按钮在单击时除了更改文本（我希望它执行）外什么都不做。

在布局中，我将顶部文本视图用作占位符，以检查下方的切换按钮是否与其执行相同的操作。

是否可以复制按钮点击动画？

这是 Java 代码：

package com.example.testttsactivity;
import android.os.Build;
import android.speech.tts.TextToSpeech;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.TextView;
import android.widget.ToggleButton;

import androidx.appcompat.app.AppCompatActivity;

import java.util.Locale;

public class MainActivity extends AppCompatActivity implements TextToSpeech.OnInitListener {
    TextView speakText;
    TextToSpeech textToSpeech;
    ToggleButton toggle;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        speakText = findViewById(R.id.txtToSay);
        toggle = findViewById(R.id.toggleButton);
        textToSpeech = new TextToSpeech(this, this);

        toggle.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (toggle.isChecked()){
                    textToSpeak();
                } else {
                    silence();
                }
            }
        });
    }
    @Override
    public void onInit(int status) {
        if (status == TextToSpeech.SUCCESS) {
            int result = textToSpeech.setLanguage(Locale.US);
            if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED) {
                Log.e("error", "This Language is not supported");
            }
        } else {
            Log.e("error", "Failed to Initialize");
        }
    }
    @Override
    public void onDestroy() {
        if (textToSpeech != null) {
            textToSpeech.stop();
            textToSpeech.shutdown();
        }
        super.onDestroy();
    }
    private void textToSpeak() {
        String text = speakText.getText().toString();
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            textToSpeech.speak(text, TextToSpeech.QUEUE_FLUSH, null, null);
        }
        else {
            textToSpeech.speak(text, TextToSpeech.QUEUE_FLUSH, null);
        }
    }

    private void silence() {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            textToSpeech.speak("", TextToSpeech.QUEUE_FLUSH, null, null);
        }
        else {
            textToSpeech.speak("", TextToSpeech.QUEUE_FLUSH, null);
        }
    }
}

和 xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:id="@+id/txtToSay"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text='"Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="60dp"
        android:orientation="horizontal">

        <TextView
            android:id="@+id/textView"
            android:layout_width="10dp"
            android:layout_height="match_parent"
            android:layout_marginStart="15dp"
            android:layout_marginEnd="15dp"
            android:layout_weight="1"
            android:background="?android:attr/selectableItemBackground"
            android:clickable="true"
            android:drawableTop="@android:drawable/ic_menu_call"
            android:focusable="true"
            android:text="listen"
            android:textAlignment="center" />

    </LinearLayout>

    <ToggleButton
        android:id="@+id/toggleButton"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@android:color/transparent"
        android:drawableTop="@android:drawable/ic_menu_call"
        android:text="listen"
        android:textAppearance="@style/TextAppearance.AppCompat.Body1"
        android:textColor="#8A000000"
        android:textOff="listen"
        android:textOn="stop" />

</LinearLayout>

任何帮助将不胜感激，谢谢！

这种效果称为纹波。您需要制作自定义背景

例如，为 API 21+ 创建 bg_ripple.xml：

<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
    android:color="@android:color/darker_gray">
    <item >
        <shape android:shape="rectangle">
            <solid android:color="@android:color/transparent" /> 
        </shape>
    </item>
</ripple>

或 21 岁以下

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <shape android:shape="rectangle">
            <solid android:color="@android:color/darker_gray" />
        </shape>
    </item>
    <item>
        <shape android:shape="rectangle">
            <solid android:color="@android:color/transparent" />
        </shape>
    </item>
</selector>

并在 Toggle Buttton 中使用它

<ToggleButton
        android:id="@+id/toggleButton"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/bg_ripple" // here
        android:drawableTop="@android:drawable/ic_menu_call"
        android:text="listen"
        android:textAppearance="@style/TextAppearance.AppCompat.Body1"
        android:textColor="#8A000000"
        android:textOff="listen"
        android:textOn="stop" />
