1.普通对话框
代码如下：
private void SimpleDialog() { btn1 = (Button) findViewById(R.id.btn_1); btn1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //创建构造者 AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this); //添加对话框内容 builder.setIcon(R.mipmap.ic_launcher); builder.setTitle("对话框"); builder.setMessage("确认删除吗？"); builder.setPositiveButton("确认", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(MainActivity.this, "确认删除", Toast.LENGTH_SHORT).show(); } }); builder.setNegativeButton("取消", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(MainActivity.this, "取消删除", Toast.LENGTH_SHORT).show(); } }); //创建对话框 AlertDialog alertDialog = builder.create(); //显示对话框 alertDialog.show(); } });}2.单选对话框
代码如下：
private void SelectDialog() { btn2 = (Button) findViewById(R.id.btn_2); btn2.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this); builder.setIcon(R.mipmap.ic_launcher_round); builder.setTitle("单选框"); builder.setPositiveButton("确认", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(MainActivity.this, "确认", Toast.LENGTH_SHORT).show(); } }); final String[] str = {"java", "php", "python"}; builder.setSingleChoiceItems(str, 2, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(MainActivity.this, "" + str[which], Toast.LENGTH_SHORT).show(); } }); //创建对话框 AlertDialog alertDialog = builder.create(); //显示对话框 alertDialog.show(); } });}3.复选对话框
代码如下：
private void MuliteDialog() { btn3 = findViewById(R.id.btn_3); btn3.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //初始化数据 final String[] str = {"java", "php", "python"}; final boolean[] booleans = {false, false, false}; AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this); builder.setIcon(R.mipmap.ic_launcher_round); builder.setTitle("复选框"); builder.setMultiChoiceItems(str, booleans, new DialogInterface.OnMultiChoiceClickListener() { @Override public void onClick(DialogInterface dialog, int which, boolean isChecked) { booleans[which] = isChecked; } }); builder.setPositiveButton("确认", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { for (int i = 0; i < booleans.length; i++) { if (booleans[i]) { int count = i + 1; Toast.makeText(MainActivity.this, "勾选" + count + "项", Toast.LENGTH_SHORT).show(); } } } }); //创建对话框 AlertDialog alertDialog = builder.create(); //显示对话框 alertDialog.show(); } });}4.自定义message对话框
代码如下：
private void CustomMsgDialog() { btn4 = findViewById(R.id.btn_4); btn4.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this); builder.setTitle("自定义对话框"); View view = LayoutInflater.from(MainActivity.this).inflate(R.layout.customer_dialog, null); final TextView tv_msg = view.findViewById(R.id.tv_msg); tv_msg.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Toast.makeText(MainActivity.this, "" + tv_msg.getText(), Toast.LENGTH_SHORT).show(); } }); //将视图插入到对话框中 builder.setView(view); //确定按钮 builder.setPositiveButton("OK", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(MainActivity.this, "确定", Toast.LENGTH_SHORT).show(); } }); AlertDialog alertDialog = builder.create(); alertDialog.show(); } });}5.水平进度对话框
代码如下：
private void PlaneProgressDialog() { btn5 = findViewById(R.id.btn_5); btn5.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { final ProgressDialog progressDialog = new ProgressDialog(MainActivity.this); progressDialog.setMessage("正在下载..."); //设置风格 //水平 progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); //模糊(圆圈)// progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER); progressDialog.setMax(100); progressDialog.show(); //模拟定时器 final Timer timer = new Timer(); /** * 三个参数 * 1.TimerTask任务 * 2.几秒后执行 * 3.每隔几秒执行一次 */ timer.schedule(new TimerTask() { int progress = 0; @Override public void run() { if (progress == 100) { timer.cancel();//取消定时器 progressDialog.dismiss();//消失 } progressDialog.setProgress(progress++); } }, 1, 100);//1秒后执行，每隔100毫秒执行一次 } }); }6.日期对话框
代码如下：
private void DataDialog() {/** * * * @param context 上下文 * @param listener 监听器 * @param year 默认的年 * @param month 默认的月 * @param dayOfMonth 默认的日 */ btn6 = findViewById(R.id.btn_6); btn6.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //获取日历对象 final Calendar calendar = Calendar.getInstance(); new DatePickerDialog(MainActivity.this, new DatePickerDialog.OnDateSetListener() { @Override public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) { Toast.makeText(MainActivity.this, year+"年"+(month+1)+"月"+dayOfMonth+"日", Toast.LENGTH_SHORT).show(); } },calendar.get(Calendar.YEAR),calendar.get(Calendar.MONTH),calendar.get(Calendar.DAY_OF_MONTH)).show(); } });}7.时间对话框
代码如下：
private void TimeDialog() { btn7 = findViewById(R.id.btn_7); btn7.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Calendar calendar = Calendar.getInstance(); new TimePickerDialog(MainActivity.this, new TimePickerDialog.OnTimeSetListener() { @Override public void onTimeSet(TimePicker view, int hourOfDay, int minute) { Toast.makeText(MainActivity.this, hourOfDay+"："+minute, Toast.LENGTH_SHORT).show(); } },calendar.get(Calendar.HOUR),calendar.get(Calendar.MINUTE),true).show();//isHourView是否采用24小时进制 } });}8.用户自定义对话框
首先需要用户自定义对话框，上布局文件：
<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#11ffffff"> <LinearLayout android:layout_width="300dp" android:layout_height="wrap_content" android:layout_centerInParent="true" android:orientation="vertical"> <TextView android:id="@+id/title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:layout_marginTop="10dp" android:text="警告" android:textColor="#38ADFF" android:textSize="16sp"/> <TextView android:id="@+id/message" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_margin="20dp" android:layout_gravity="center" android:text="保护视力，少玩手机"/> <View android:layout_width="match_parent" android:layout_height="1px" android:layout_marginTop="15dp" android:background="#E4E4E4"/> <LinearLayout android:layout_width="match_parent" android:layout_height="40dp" android:orientation="horizontal"> <Button android:id="@+id/no" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="1" android:layout_marginLeft="10dp" android:background="@null" android:gravity="center" android:lines="1" android:text="取消" android:textColor="#7D7D7D" android:textSize="16sp"/> <View android:layout_width="1px" android:layout_height="match_parent" android:background="#E4E4E4"/> <Button android:id="@+id/yes" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="1" android:layout_marginRight="10dp" android:background="@null" android:gravity="center" android:lines="1" android:text="确定" android:textColor="#38ADFF" android:textSize="16sp"/> </LinearLayout> </LinearLayout></RelativeLayout>有了布局文件，接下来就是要创建类，来设置具体怎么使用
public class UserDefinedDialog extends Dialog { private TextView title; private TextView message; private Button no; private Button yes; private String titleStr;//从外界设置的title文本 private String messageStr;//从外界设置的消息文本 //确定文本和取消文本的显示的内容 private String yesStr, noStr; //取消按钮被点击了的监听器 private onNoOnclickListener noOnclickListener; //确定按钮被点击了的监听器 private onYesOnclickListener yesOnclickListener; public UserDefinedDialog(Context context) { super(context); } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.userdefined_dialog); //初始化控件 initViews(); //初始化数据 initDatas(); //初始化控件事件 initEvents(); } private void initEvents() { //设置确定按钮被点击后，向外界提供监听 yes.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (yesOnclickListener!=null){ yesOnclickListener.onYesOnclick(); } } }); //设置取消按钮的监听 no.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (noOnclickListener!=null){ noOnclickListener.onNoClick(); } } }); } private void initDatas() { //做非空判断，防止数据为空 if (titleStr!=null){ title.setText(titleStr); } if (messageStr!=null){ message.setText(messageStr); } if (yesStr!=null){ yes.setText(yesStr); } if (noStr!=null){ no.setText(noStr); } } private void initViews() { title = (TextView) findViewById(R.id.title); message = (TextView) findViewById(R.id.message); no = (Button) findViewById(R.id.no); yes = (Button) findViewById(R.id.yes); } //从外界Activity为UserDefinedDialog设置标题 public void setTitleStr(String titleStr) { this.titleStr = titleStr; } public void setMessageStr(String messageStr) { this.messageStr = messageStr; } //自定义点击事件 public interface onNoOnclickListener { public void onNoClick(); } public interface onYesOnclickListener { public void onYesOnclick(); } public void setNoOnclickListener(String str,onNoOnclickListener noOnclickListener) { if (str!=null){ noStr = str; } this.noOnclickListener = noOnclickListener; } public void setYesOnclickListener(String str,onYesOnclickListener yesOnclickListener) { if (str!=null){ yesStr = str; } this.yesOnclickListener = yesOnclickListener; }}最后在MainActivity中将自定义的对话框进行创建，添加内容即可
private void UserDefinedDialog() { btn8 = findViewById(R.id.btn_8); btn8.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { final UserDefinedDialog dialog = new UserDefinedDialog(MainActivity.this); //通过自己设置的方法，跟新对话框内容 dialog.setTitleStr("这是title"); dialog.setMessageStr("这是提示信息"); //确定按钮 dialog.setYesOnclickListener("yes", new UserDefinedDialog.onYesOnclickListener() { @Override public void onYesOnclick() { Toast.makeText(MainActivity.this, "按钮被点击", Toast.LENGTH_SHORT).show(); dialog.dismiss(); } }); //取消按钮 dialog.setNoOnclickListener("no", new UserDefinedDialog.onNoOnclickListener() { @Override public void onNoClick() { Toast.makeText(MainActivity.this, "按钮被点击", Toast.LENGTH_SHORT).show(); dialog.dismiss(); } }); //显示对话框 dialog.show(); } });}最终效果：
