<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!--未按下状态的设置-->
    <item android:state_pressed="false">
        <!--设置背景形状-->
        <shape xmlns:android="http://schemas.android.com/apk/res/android">
            <!--设置圆角-->
            <corners android:radius="10dp" />
            <!--设置背景颜色-->
            <solid android:color="#FFFFFF" />
            <!--设置边框-->
            <stroke android:width="1dp" android:color="#4AB17C" />
        </shape>
    </item>
    <!--按下状态的设置-->
    <item android:state_pressed="true">
        <shape xmlns:android="http://schemas.android.com/apk/res/android">
            <corners android:radius="10dp" />
            <solid android:color="#4AB17C" />
        </shape>
    </item>
</selector>

3.设置点击button，button上文字变色

在res文件下的drawable下新建一个xml，命名为text_color_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!--按下时Button文字颜色-->
    <item android:color="@color/white" android:state_pressed="true"></item>
    <!--未按下时Button文字颜色-->
    <item android:color="@android:color/white" android:state_pressed="false"></item>

</selector>

三.Activity中设置Button属性

1.点击事件

 Button btn = findViewById(R.id.button);
        //点击事件
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //输出对应的信息
                Log.e("再见孙悟空", "点击事件触发:  " );
            }
        });

2.长按事件

  //长按事件
        btn.setOnLongClickListener(new View.OnLongClickListener() {
            @Override
            public boolean onLongClick(View v) {
                Log.e("再见孙悟空", "长按事件触发: " );
                return false;
            }
        });

3.触摸事件

//触摸事件
        btn.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View view, MotionEvent motionEvent) {
                switch (motionEvent.getAction()){

                    case MotionEvent.ACTION_DOWN://按下

                        break;
                    case MotionEvent.ACTION_UP://抬起

                        break;
                    case MotionEvent.ACTION_MOVE://滑动

                        break;
                }
                return false;
            }
        });

四.Demo示例

import android.view.MotionEvent;
import android.view.View;
import android.widget.Button;

import androidx.appcompat.app.AppCompatActivity;

public class ButtonActivity extends AppCompatActivity {

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

    private void initView() {
        Button btn = findViewById(R.id.button);
        //点击事件
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //输出对应的信息
                Log.e("再见孙悟空", "点击事件触发:  " );
            }
        });

        //长按事件
        btn.setOnLongClickListener(new View.OnLongClickListener() {
            @Override
            public boolean onLongClick(View v) {
                Log.e("再见孙悟空", "长按事件触发: " );
                return false;
            }
        });

        //触摸事件
        btn.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View view, MotionEvent motionEvent) {
                switch (motionEvent.getAction()){

                    case MotionEvent.ACTION_DOWN://按下

                        break;
                    case MotionEvent.ACTION_UP://抬起

                        break;
                    case MotionEvent.ACTION_MOVE://滑动

                        break;
                }
