Android有四种默认的Dialog实现:AlertDialog、ProgressDialog、DatePickerDialog、TimePickerDialog。另外你还可以继承android.app.Dialog实现自已的dialog。
1.AlertDialog是一种能构造默认的零、一、二、三个按钮的对话框、单选框、多选框、列表等。
2.ProgressDialog是继函大自AlertDialog，除了AlertDialog功能外，它还能显视进度圈或条的对话框。
3.DatePickerDialog/TimePickerDialog是分别能让用户选择日期和时间的对话框。
-------------------
AlertDialog部分：
1.不同个数按钮选择的Dialog:
code
new AlertDialog.Builder(AlertDialogSamples.this)
.setIcon(R.drawable.alert_dialog_icon)
.setTitle(R.string.alert_dialog_two_buttons_msg)
.setMessage(R.string.alert_dialog_two_buttons2_msg)
.setPositiveButton(R.string.alert_dialog_ok, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
/* User clicked OK so do some stuff */
}
})
.setNeutralButton(R.string.alert_dialog_something, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
/* User clicked Something so do some stuff */
}
})
.setNegativeButton(R.string.alert_dialog_cancel, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
/* User clicked Cancel so do some stuff */
}
})
.create();
注意：每个setXX都是可选可不选的。例如:可以都不选只选setMessage("--")得到和toast一样效果的dialog。
2.列表Dialog:
code
new AlertDialog.Builder(AlertDialogSamples.this)
.setTitle(R.string.select_dialog)
.setItems(R.array.select_dialog_items, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
/* User clicked so do some stuff */
String[] items = getResources().getStringArray(R.array.select_dialog_items);
new AlertDialog.Builder(AlertDialogSamples.this)
.setMessage("You selected: " + which + " , " + items[which])
.show();
}
})
.create();
3.单选Dialog:
code
new AlertDialog.Builder(AlertDialogSamples.this)
.setIcon(R.drawable.alert_dialog_icon)
.setTitle(R.string.alert_dialog_single_choice)
.setSingleChoiceItems(R.array.select_dialog_items2, 0, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
/* User clicked on a radio button do some stuff */
}
})
.setPositiveButton(R.string.alert_dialog_ok, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
/* User clicked Yes so do some stuff */
}
})
.setNegativeButton(R.string.alert_dialog_cancel, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
/* User clicked No so do some stuff */
}
})
.create();
4.多选Dialog:
code
new AlertDialog.Builder(AlertDialogSamples.this)
.setIcon(R.drawable.ic_popup_reminder)
.setTitle(R.string.alert_dialog_multi_choice)
.setMultiChoiceItems(R.array.select_dialog_items3,
new boolean[]{false, true, false, true, false, false, false},
new DialogInterface.OnMultiChoiceClickListener() {
public void onClick(DialogInterface dialog, int whichButton,
boolean isChecked) {
/* User clicked on a check box do some stuff */
}
})
.setPositiveButton(R.string.alert_dialog_ok, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
/* User clicked Yes so do some stuff */
}
})
.setNegativeButton(R.string.alert_dialog_cancel, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
/* User clicked No so do some stuff */
}
})
.create();
5.可输入Dialog:
code
LayoutInflater factory = LayoutInflater.from(this);
final View textEntryView = factory.inflate(R.layout.alert_dialog_text_entry, null);
return new AlertDialog.Builder(AlertDialogSamples.this)
.setIcon(R.drawable.alert_dialog_icon)
.setTitle(R.string.alert_dialog_text_entry)
.setView(textEntryView)
.setPositiveButton(R.string.alert_dialog_ok, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
/* User clicked OK so do some stuff */
}
})
.setNegativeButton(R.string.alert_dialog_cancel, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
/* User clicked cancel so do some stuff */
}
})
.create();
----------------------------------
ProgressDialog部分：
code
new ProgressDialog(AlertDialogSamples.this);
mProgressDialog.setIcon(R.drawable.alert_dialog_icon);
mProgressDialog.setTitle(R.string.select_dialog);
mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
mProgressDialog.setMax(MAX_PROGRESS);
mProgressDialog.setButton(getText(R.string.alert_dialog_hide), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
/* User clicked Yes so do some stuff */
}
});
mProgressDialog.setButton2(getText(R.string.alert_dialog_cancel), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
/* User clicked No so do some stuff */
}
});
----------------------------------
自定义Dialog的样式：
mycode
final LayoutInflater factory = LayoutInflater.from(MobileMap.this);
final View dialogview = factory.inflate(R.layout.navigation, null);
((TextView) dialogview.findViewById(R.id.start)).setText("起始地点:");
((EditText) dialogview.findViewById(R.id.startedit)).setText("当前位置");
((TextView) dialogview.findViewById(R.id.end)).setText("到达地点:");
((EditText) dialogview.findViewById(R.id.endedit)).setText(" ");
Builder builder = new Builder(MobileMap.this);
builder.setTitle("****导航****");
builder.setView(dialogview);
builder.setPositiveButton(android.R.string.ok, new AlertDialog.OnClickListener()
{
public void onClick(DialogInterface dialog, int which)
{
// 点击确定之后
String value = ((EditText) dialogview.findViewById(R.id.EditText01)).getText().toString().trim();
if (value != "")
{
searchName(value);
}
}
});
builder.setNegativeButton(android.R.string.cancel, new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int which)
{
dialog.cancel();
}
});
builder.setOnCancelListener(new DialogInterface.OnCancelListener()
{
public void onCancel(DialogInterface dialog)
{
dialog.cancel();
}
});
builder.show();
DatePickerDialog或DatePickerDialog部分：
注意：所有例子都在Android自带的ApiDemos例子中！(除了自定义样式那个外）
