全部嗨!
如果我显示DatePickerDialog并单击按钮否定,接下来我想显示AlertDialog但他崩溃了。如果我显示DatePickerDialog并单击button_positive - 那么一切都很好(AlertDialog可以显示)。
protected Dialog onCreateDialog(int id) {
if (id == DIALOG_DATE) {
final DatePickerDialog tpd = new DatePickerDialog(this, myCallBack, 2000, 02, 02);
tpd.setOnShowListener(new DialogInterface.OnShowListener() {
public void onShow(final DialogInterface dialog) {
Button d = tpd.getButton(DatePickerDialog.BUTTON_NEGATIVE);
d.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
tpd.dismiss();
}
});
}
});
return tpd;
}
if (id == DIALOG_ABOUT) {
final LinearLayout view = (LinearLayout) getLayoutInflater()
.inflate(R.layout.dialog_about, null);
final AlertDialog adb = new AlertDialog.Builder(this)
.setView(view)
.setTitle("О программе")
.setIcon(android.R.drawable.ic_dialog_info)
.setPositiveButton(R.string.next,
new Dialog.OnClickListener() {
public void onClick(DialogInterface d, int which) {
// Do nothing here. We override the onclick
}
}).create();
adb.setOnShowListener(new DialogInterface.OnShowListener() {
public void onShow(final DialogInterface dialog) {
Button b = adb.getButton(AlertDialog.BUTTON_POSITIVE);
b.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
adb.dismiss();
}
});
}
});
return adb;
}
return super.onCreateDialog(id);
}
