6.自定义对话框

• 创建自定义对话框样式，这里以mydialog.xml为例；
• 创建MyDialog类；
• MainActivity调用MyDialog类

创建mydialog.xml

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

        android:id="@+id/tv_1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:text="提示"
        android:background="#E619E3"
        android:textSize="28sp"/>
    <TextView
        android:id="@+id/tv_2"
        android:layout_width="match_parent"
        android:layout_height="100dp"
        android:gravity="center"
        android:text="你真的要离开吗"
        android:textColor="#ff0400"
        android:background="@drawable/log3"
        android:textSize="28sp"/>
    <LinearLayout
        android:id="@+id/ll_1"
        android:orientation="horizontal"
        android:layout_width="match_parent"
        android:layout_height="50sp"
        android:gravity="center"
        android:background="#D3DF26">
        <Button
            android:id="@+id/btn_1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="残忍离开"
            android:textSize="24sp"
            android:background="#06F18B"
            android:layout_marginRight="30dp"
            android:onClick="okclick"/>
        <Button
            android:id="@+id/btn_2"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:textSize="28sp"
            android:text="马上进入"
            android:background="#8284E1"
           android:layout_marginLeft="30dp"
            android:onClick="canclick"/>
    </LinearLayout>

</LinearLayout>

创建MyDialog类

package com.krisantisce.androiddialog;
import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.view.Window;
import android.widget.Button;
import android.widget.TextView;
import androidx.annotation.NonNull;

public class MyDialog extends Dialog {    //继承父类
    private String dialogName;
    public MyDialog(@NonNull Context context, String dialogName) {
        super(context);
        this.dialogName = dialogName;

    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);  // 去除标题
        setContentView(R.layout.mydialog);              // 引入自定义对话框布局
        TextView textView = findViewById(R.id.tv_2);
        Button button_no = findViewById(R.id.btn_1);
        Button button_ok = findViewById(R.id.btn_2);
        //设置自定义对话框显示内容
        textView.setText(dialogName);
        //给按钮设置点击事件
        button_ok.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

            }
        });

        button_no.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // 把对话框关闭
                dismiss();
            }
        });
    }
}

MainActivity调用MyDialog类

package com.krisantisce.androiddialog;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;

public class MainActivity extends AppCompatActivity {

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

        MyDialog myDialog = new MyDialog(this,null);
        myDialog.show();

    }
}
