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();
}
}
