给底部的对话框添加移动动画效果

可通过Window.setWindowAnimations(int resId)设置

SharingDialog.java

package com.bu_ish.sharing_dialog_example;
    
    import android.app.Dialog;
    import android.content.Context;
    import android.content.DialogInterface;
    import android.os.Bundle;
    import android.view.Gravity;
    import android.view.View;
    import android.view.WindowManager;
    import android.widget.Toast;
    
    public class SharingDialog extends Dialog {
        public SharingDialog(Context context) {
            super(context, R.style.SharingDialog);
            setCanceledOnTouchOutside(false);
            setOnCancelListener(new OnCancelListener() {
                @Override
                public void onCancel(DialogInterface dialog) {
                    Toast.makeText(getContext(), "已取消", Toast.LENGTH_SHORT).show();
                }
            });
            getWindow().setWindowAnimations(R.style.SharingDialogAnimation);
        }
    
        @Override
        public void show() {
            super.show();
            WindowManager.LayoutParams layoutParams = getWindow().getAttributes();
            layoutParams.width = WindowManager.LayoutParams.MATCH_PARENT;
            layoutParams.gravity = Gravity.BOTTOM;
            getWindow().setAttributes(layoutParams);
        }
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.dialog_sharing);
            findViewById(R.id.cancelTextView).setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    cancel();
                }
            });
        }
    }

动画style

对话框显示动画

sharing\_dialog\_show\_animation.xml

<?xml version="1.0" encoding="utf-8"?>
    <set xmlns:android="http://schemas.android.com/apk/res/android">
        <translate
            android:duration="500"
            android:fromYDelta="100%p"
            android:toYDelta="0" />
    </set>

对话框关闭动画

sharing\_dialog\_dismiss\_animation.xml

<?xml version="1.0" encoding="utf-8"?>
    <set xmlns:android="http://schemas.android.com/apk/res/android">
        <translate
            android:duration="500"
            android:fromYDelta="0"
            android:toYDelta="100%p" />
    </set>
