sayWindows.setView(saySomething);
final AlertDialog mAlertDialog = sayWindows.create();
mAlertDialog.setOnShowListener(new DialogInterface.OnShowListener() {
@Override
public void onShow(DialogInterface dialog) {
Button b = mAlertDialog.getButton(AlertDialog.BUTTON_POSITIVE);
b.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// TODO Do something

based on the most voted answer for How to prevent a dialog from closing when a button is clicked
基于如何在单击按钮时防止对话框关闭的投票最多的答案
final AlertDialog d = new AlertDialog.Builder(context)
.setView(v)
.setTitle(R.string.my_title)
.setPositiveButton(android.R.string.ok, null) //Set to null. We override the onclick
.setNegativeButton(android.R.string.cancel, null)
.create();
d.setOnShowListener(new DialogInterface.OnShowListener() {
@Override
public void onShow(DialogInterface dialog) {
Button b = d.getButton(AlertDialog.BUTTON_POSITIVE);
b.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// TODO Do something
}
});
}
});
I believe you need to override the positive button's handler. Add your logic to dismiss the dialog when a certain condition is met.
我相信您需要覆盖正按钮的处理程序。添加您的逻辑以在满足特定条件时关闭对话框。

Even Simpler:
更简单：
final AlertDialog alertDialog = new AlertDialog.Builder(context).setView(v)
.setPositiveButton(android.R.string.ok, null)
.setNegativeButton(android.R.string.cancel, null)
.show();
Button b = alertDialog.getButton(AlertDialog.BUTTON_POSITIVE);
b.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
//Do Your thing
}
});

I do it like this:
我这样做：
final AlertDialog dialog = new AlertDialog.Builder(this)
.setCancelable(false)
.setPositiveButton("YES", null)
.setNegativeButton("NO", null)
.show();
Button positiveButton = dialog.getButton(AlertDialog.BUTTON_POSITIVE);
positiveButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Toast.makeText(SysManagerActivity.this, "dialog is open", Toast.LENGTH_SHORT).show();
}
});
