Android十大常用对话框
- 一、对话框效果
- 二、代码
最近老师叫我们整理android常用的对话框，我整理了十种对话框，用于分享交流，希望指正！
一、对话框效果
主界面
1.普通对话框
2.单选对话框
3.多选对话框
4.列表对话框
5.不带进度条对话框
6.带进度条对话框
7.自定义布局对话框
8.自定义对话框
9.日期对话框
10.时间对话框
二、代码
1.将所有的对话框方法封装在DialogBox类中
package com.example.homeworkfour;import android.app.Activity;import android.app.AlertDialog;import android.app.DatePickerDialog;import android.app.Dialog;import android.app.ProgressDialog;import android.app.TimePickerDialog;import android.content.DialogInterface;import android.icu.util.Calendar;import android.os.Build;import android.view.View;import android.widget.Button;import android.widget.DatePicker;import android.widget.EditText;import android.widget.TimePicker;import android.widget.Toast;import androidx.annotation.RequiresApi;public class DialogBox { /** * 1.普通对话框 */ protected void ordinaryDialogBox(final Activity activity){ AlertDialog.Builder dialogBox = new AlertDialog.Builder(activity); dialogBox.setTitle("普通对话框"); dialogBox.setMessage("你要离开吗？"); dialogBox.setPositiveButton("确定", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(activity,"我要离开！",Toast.LENGTH_SHORT).show(); } }); dialogBox.setNegativeButton("取消", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(activity,"我不想离开！",Toast.LENGTH_SHORT).show(); } }); dialogBox.create().show(); } /** * 2.单选对话框 */ protected void radioDialogBox(final Activity activity){ final AlertDialog.Builder dialogBox = new AlertDialog.Builder(activity); dialogBox.setTitle("你最喜欢的科目是？"); /* *因为setMessage和setSingleChoiceItems的显示区域互相冲突， *所以它们不能被同时使用，在这里我们必须注释掉掉这下面这行代码， * 但是，我们仍然可以使用setTitle()来设置标题或消息 */ //dialogBox.setMessage(""); final String[] items = {"物理","化学","生物","历史"}; dialogBox.setSingleChoiceItems(items,-1, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(activity,"你最喜欢的科目是"+items[which],Toast.LENGTH_SHORT).show(); //选择一个选项之后，就立即关闭对话框 dialog.dismiss(); } }); dialogBox.create().show(); } /** * 3.多选对话框 */ protected void multipleDialogBox(final Activity activity){ AlertDialog.Builder dialogBox = new AlertDialog.Builder(activity); dialogBox.setTitle("你喜欢哪些食物？"); final String[] items = {"胡萝卜","白菜","菠菜","土豆","黄瓜","西红柿"}; //标识选项的状态，false为未选中，true为选中 final boolean[] check = {false,false,false,false,false,false}; dialogBox.setMultiChoiceItems(items, check, new DialogInterface.OnMultiChoiceClickListener() { @Override public void onClick(DialogInterface dialog, int which, boolean isChecked) { //当被选中时，选项的状态为true,否则为false if (isChecked){ check[which] = true; Toast.makeText(activity,"你选中了"+items[which],Toast.LENGTH_SHORT).show(); }else { check[which] = false; Toast.makeText(activity,"你取消了"+items[which],Toast.LENGTH_SHORT).show(); } } }); dialogBox.setPositiveButton("确定", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { String str = ""; for (int i = 0; i < check.length; i++) { if (check[i]){ str = str + "," + items[i]; } } //显示被选中的内容 if(str!="") { Toast.makeText(activity, "你喜欢" + str, Toast.LENGTH_SHORT).show(); } } }); dialogBox.create().show(); } /** * 4.列表对话框 */ protected void listDialogBox(final Activity activity){ AlertDialog.Builder dialogBox = new AlertDialog.Builder(activity); dialogBox.setTitle("课程安排："); final String[] items = {"第一节（数学）","第二节（地理）","第三节（历史）","第四节（美术）"}; dialogBox.setItems(items, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(activity,items[which],Toast.LENGTH_SHORT).show(); } }); dialogBox.create().show(); } /** * 5.不带进度条对话框 */ protected void noProgressDialogBox(Activity activity){ ProgressDialog dialogBox = new ProgressDialog(activity); dialogBox.setProgressStyle(ProgressDialog.STYLE_SPINNER); dialogBox.setTitle("不带进度条对话框"); dialogBox.setMessage("加载中~"); dialogBox.show(); } /** * 6.带进度条对话框 */ protected void progressDialogBox(Activity activity){ final ProgressDialog dialogBox = new ProgressDialog(activity); //水平样式 dialogBox.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); dialogBox.setTitle("进度条对话框"); dialogBox.setMessage("加载中~"); dialogBox.show(); //显示进度条进度 new Thread(new Runnable() { @Override public void run() { // TODO Auto-generated method stub for (int j = 0; j <= 100; j++) { try { Thread.sleep(200); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } dialogBox.setProgress(j); } //加载完毕，退出对话框 dialogBox.dismiss(); } }).start(); } /** * 7.自定义布局对话框 */ protected void customLayoutDialogBox(final Activity activity){ final AlertDialog.Builder dialogBox = new AlertDialog.Builder(activity); //创建一个view，并且将自定义布局对话框的布局加入view中 View view = View.inflate(activity,R.layout.custom_layout,null); dialogBox.setView(view); final Dialog dialog = dialogBox.create(); final EditText editText1 = view.findViewById(R.id.editText1); final EditText editText2 = view.findViewById(R.id.editText2); Button button1 = view.findViewById(R.id.button1); Button button2 = view.findViewById(R.id.button2); //设置监听器 button1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Toast.makeText(activity,"退出",Toast.LENGTH_SHORT).show(); dialog.dismiss(); } }); button2.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Toast.makeText(activity,"用户名："+editText1.getText().toString()+" 密码："+ editText2.getText().toString(),Toast.LENGTH_SHORT).show(); dialog.dismiss(); } }); dialog.show(); } /** * 8.自定义对话框 */ protected void customDialogBox(final Activity activity){ final CustomDialogBox dialogBox = new CustomDialogBox(activity); dialogBox.setTitle("自定义对话框"); dialogBox.setContent("你要离开吗？"); dialogBox.setOnYesClick("确定", new CustomDialogBox.OnYesClickListener() { @Override public void confirm() { Toast.makeText(activity,"点击了--确定--按钮",Toast.LENGTH_LONG).show(); dialogBox.dismiss(); } }); dialogBox.setOnNoClick("取消", new CustomDialogBox.OnNoClickListener() { @Override public void cancel() { Toast.makeText(activity,"点击了--取消--按钮",Toast.LENGTH_LONG).show(); dialogBox.dismiss(); } }); dialogBox.show(); } /** * 9.日期对话框 */ @RequiresApi(api = Build.VERSION_CODES.N) protected void dateDialogBox(final Activity activity){ //创建Calendar对象 Calendar calendar = Calendar.getInstance(); DatePickerDialog dialogBox = new DatePickerDialog(activity, new DatePickerDialog.OnDateSetListener() { @Override public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) { //显示选择的日期 /* 这里请大家注意，为什么月份是(month+1),因为month代表的是上年底与现在相差的月份数， 比如选择日期：1月15日，它与上年底相差的月份没有1个月，只有15天，那么month=0, 当日期：2月15，它与上年底相差的日子为1个月15天，那么month=1。 */ Toast.makeText(activity,year+"年 "+(month+1)+"月 "+dayOfMonth+"日",Toast.LENGTH_SHORT).show(); } //刚打开日期对话框，默认选择当前日期 }, calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH)); //显示日期对话框 dialogBox.show(); } /** * 10.时间对话框 */ @RequiresApi(api = Build.VERSION_CODES.N) protected void timeDialogBox(final Activity activity){ //创建Calendar对象 final Calendar calendar = Calendar.getInstance(); TimePickerDialog dialogBox = new TimePickerDialog(activity, new TimePickerDialog.OnTimeSetListener() { @Override public void onTimeSet(TimePicker view, int hourOfDay, int minute) { //显示选择的时间 Toast.makeText(activity,hourOfDay+"点 "+minute+"分",Toast.LENGTH_SHORT).show(); } },calendar.get(Calendar.HOUR), calendar.get(Calendar.MINUTE),true); //显示时间对话框 dialogBox.show(); }}2.通过new一个DialogBox实例，分别调用各种对话框，当点击了相应的按钮，就实现相应的对话框
package com.example.homeworkfour;import android.os.Build;import android.os.Bundle;import android.view.View;import android.widget.Button;import androidx.annotation.RequiresApi;import androidx.appcompat.app.AppCompatActivity;public class MainActivity extends AppCompatActivity { //定义全局变量 private Button button1, button2, button3, button4, button5, button6, button7,button8,button9,button10; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); final DialogBox dialogBox=new DialogBox(); //绑定控件并为按钮设置监听器 button1=findViewById(R.id.button1); button1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { dialogBox.ordinaryDialogBox(MainActivity.this); } }); button2=findViewById(R.id.button2); button2.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { dialogBox.radioDialogBox(MainActivity.this); } }); button3=findViewById(R.id.button3); button3.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { dialogBox.multipleDialogBox(MainActivity.this); } }); button4=findViewById(R.id.button4); button4.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { dialogBox.listDialogBox(MainActivity.this); } }); button5=findViewById(R.id.button5); button5.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { dialogBox.noProgressDialogBox(MainActivity.this); } }); button6=findViewById(R.id.button6); button6.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { dialogBox.progressDialogBox(MainActivity.this); } }); button7=findViewById(R.id.button7); button7.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { dialogBox.customLayoutDialogBox(MainActivity.this); } }); button8=findViewById(R.id.button8); button8.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { dialogBox.customDialogBox(MainActivity.this); } }); button9=findViewById(R.id.button9); button9.setOnClickListener(new View.OnClickListener() { @RequiresApi(api = Build.VERSION_CODES.N) @Override public void onClick(View v) { dialogBox.dateDialogBox(MainActivity.this); } }); button10=findViewById(R.id.button10); button10.setOnClickListener(new View.OnClickListener() { @RequiresApi(api = Build.VERSION_CODES.N) @Override public void onClick(View v) { dialogBox.timeDialogBox(MainActivity.this); } }); }}3.自定义对话框，就是利用重写Dialog实现自定义对话框
package com.example.homeworkfour;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;public class CustomDialogBox extends Dialog { private TextView title, content; private Button confirm, cancel; private String titleStr, contentStr, confirmStr, cancelStr; private Context mContext; // 按钮监听器 private OnNoClickListener onNoClickListener; private OnYesClickListener onYesClickListener; public CustomDialogBox(Context context) { super(context); this.mContext = context; } public CustomDialogBox(Context context, int theme) { super(context, theme); this.mContext = context; } @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); getWindow().requestFeature(Window.FEATURE_NO_TITLE); //使用自定义的布局 setContentView(R.layout.custom_dialog); init(); title.setText(titleStr); content.setText(contentStr); confirm.setText(confirmStr); cancel.setText(cancelStr); // 确认按钮 confirm.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View arg0) { if (onYesClickListener != null) { onYesClickListener.confirm(); } } }); // 取消按钮 cancel.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View arg0) { if (onNoClickListener != null) { onNoClickListener.cancel(); } } }); } /* * 初始化控件 */ private void init() { title = (TextView) findViewById(R.id.title); content = (TextView) findViewById(R.id.content); confirm = (Button) findViewById(R.id.confirm); cancel = (Button) findViewById(R.id.cancel); } /* * 设置取消对话框的点击事件的监听接口 */ public interface OnNoClickListener { public void cancel(); } /* * 设置确认对话框的点击事件的监听接口 */ public interface OnYesClickListener { public void confirm(); } /* * 为外部设置监听部分 */ public void setOnYesClick(String str, OnYesClickListener onYesClickListener) { if (str != null) { this.confirmStr = str; } this.onYesClickListener = onYesClickListener; } public void setOnNoClick(String str, OnNoClickListener onNoClickListener) { if (str != null) { this.cancelStr = str; } this.onNoClickListener = onNoClickListener; } /** * 为外界暴露方法，设置标题内容等 */ public void setTitle(String str) { this.titleStr = str == null ? "" : str; } public void setContent(String str) { this.contentStr = str == null ? "" : str; }}4.主界面的布局
