Android Dialog使用汇总

Dialog分类

AlertDialog

Dialog 类是对话框的基类，官方建议我们不要直接实例化它，而是使用其子类来获取实例。AlertDialog是系统提供的一个直接子类，它能帮助我们快速构建出不同类型的弹窗。接下来就看下各种类型弹窗的使用。

1、普通对话框

                AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this).setIcon(R.drawable.ic_launcher_background).setTitle("普通对话框的标题").setMessage("我是内容").setPositiveButton("确定", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {Toast.makeText(MainActivity.this, "点击了确定", Toast.LENGTH_SHORT).show();}}).setNegativeButton("取消", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {Toast.makeText(MainActivity.this, "点击了取消", Toast.LENGTH_SHORT).show();}})//Neutral按钮，显示在dialog的最左面。.setNeutralButton("不确定", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {Toast.makeText(MainActivity.this, "点击了不确定", Toast.LENGTH_SHORT).show();}});AlertDialog dialog = builder.create();dialog.show();

2、列表对话框

         String[] itemArray = {"第一个", "第二个", "第三个", "第四个", "第五个"};AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this).setIcon(R.drawable.ic_launcher_background).setTitle("列表对话框的标题").setItems(itemArray, new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {Toast.makeText(MainActivity.this, "点击了" + itemArray[which], Toast.LENGTH_SHORT).show();}});AlertDialog dialog = builder.create();dialog.show();

3、单选对话框

       String[] itemArray = {"第一个", "第二个", "第三个", "第四个", "第五个"};AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this).setIcon(R.drawable.ic_launcher_background).setTitle("单选对话框的标题").setSingleChoiceItems(itemArray, 0, new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {}}).setPositiveButton("确定", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {Toast.makeText(MainActivity.this, "点击了确定", Toast.LENGTH_SHORT).show();}}).setNegativeButton("取消", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {Toast.makeText(MainActivity.this, "点击了取消", Toast.LENGTH_SHORT).show();}});AlertDialog dialog = builder.create();dialog.show();

4、多选对话框

    String[] itemArray = {"第一个", "第二个", "第三个", "第四个", "第五个"};AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this).setIcon(R.drawable.ic_launcher_background).setTitle("多选对话框的标题").setMultiChoiceItems(itemArray, null, new DialogInterface.OnMultiChoiceClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which, boolean isChecked) {}}).setPositiveButton("确定", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {Toast.makeText(MainActivity.this, "点击了确定", Toast.LENGTH_SHORT).show();}}).setNegativeButton("取消", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {Toast.makeText(MainActivity.this, "点击了取消", Toast.LENGTH_SHORT).show();}});AlertDialog dialog = builder.create();dialog.show();

5、多选对话框

             View customView = LayoutInflater.from(MainActivity.this).inflate(R.layout.dialog_custom_view_1, null);AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this).setIcon(R.drawable.ic_launcher_background).setTitle("自定义对话框的标题").setView(customView).setPositiveButton("确定", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {Toast.makeText(MainActivity.this, "点击了确定", Toast.LENGTH_SHORT).show();}}).setNegativeButton("取消", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {Toast.makeText(MainActivity.this, "点击了取消", Toast.LENGTH_SHORT).show();}});AlertDialog dialog = builder.create();dialog.show();

6、DatePickerDialog，日期选择对话框

默认显示

         DatePickerDialog datePickerDialog = new DatePickerDialog(MainActivity.this,new DatePickerDialog.OnDateSetListener() {@Overridepublic void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {Toast.makeText(MainActivity.this, year + "-" + month + "-" + dayOfMonth, Toast.LENGTH_SHORT).show();}}, 2024, 5, 4);datePickerDialog.show();

修改对话框themeStyle为：AlertDialog.THEME_HOLO_LIGHT，效果如下：

  DatePickerDialog datePickerDialog = new DatePickerDialog(MainActivity.this,AlertDialog.THEME_HOLO_LIGHT,new DatePickerDialog.OnDateSetListener() {@Overridepublic void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {Toast.makeText(MainActivity.this,year + "-" + month + "-" + dayOfMonth, Toast.LENGTH_SHORT).show();}}, 2024, 5, 4);datePickerDialog.show();

7、TimePickerDialog，时间选择对话框

默认显示

                TimePickerDialog timePickerDialog = new TimePickerDialog(MainActivity.this, new TimePickerDialog.OnTimeSetListener() {@Overridepublic void onTimeSet(TimePicker view, int hourOfDay, int minute) {Toast.makeText(MainActivity.this, hourOfDay + ":" + minute, Toast.LENGTH_SHORT).show();}}, 9, 36, true);timePickerDialog.show();

修改对话框themeStyle为：AlertDialog.THEME_HOLO_LIGHT，效果如下：

                TimePickerDialog timePickerDialog = new TimePickerDialog(MainActivity.this, AlertDialog.THEME_HOLO_LIGHT, new TimePickerDialog.OnTimeSetListener() {@Overridepublic void onTimeSet(TimePicker view, int hourOfDay, int minute) {Toast.makeText(MainActivity.this, hourOfDay + ":" + minute, Toast.LENGTH_SHORT).show();}}, 9, 36, true);timePickerDialog.show();

8、ProgressDialog

官方已弃用，建议使用ProgressBar代替，自定义Dialog加载对话框。

Android 包含另一个名为 ProgressDialog 的对话框类，该类可显示带有进度条的对话框。此 widget 已废弃，因为它会在显示进度时阻止用户与应用互动。如果您需要指示加载进度或不确定的进度，请遵循进度和 Activity 中的设计准则，并在布局中使用 ProgressBar，而不是 ProgressDialog。

9、DialogFragment

DialogFragment是继承Fragment的，拥有和Fragment一样的生命周期。在使用时，更容易通过生命周期回调来管理弹窗。对于复杂样式的弹窗，使用DialogFragment更加方便和高效。
