Question

我在popUp窗口中有一个listView，我希望当用户点击listview中的某个项目时，popUp窗口会自动关闭。知道我该怎么做吗？

<script type="text/javascript">
function myFormat(num){
    return (num < 10)? ("0"+num): num;
}
function StartTimer(num, time){
    this.parts = time.split(':');
    this.hours = this.parts[0];
    this.minutes = this.parts[1];
    this.seconds = this.parts[2];
    this.span = $('#countdown' + num);
}
StartTimer.prototype.myTimer = function(){
    var s = this.seconds;
    var m = this.minutes;
    var h = this.hours;
    var sp = this.span;
    var t = setInterval(function(){
        s--;
        if(s == -1) {
            s = 59;
            m--;
            if(m == -1) {
                m = 59;
                h--;
                if(h == -1) {
                    alert("timer finished");
                    clearInterval(t);
                    return;
                }
            }
        }
        //console.log();
        //console.log();
        //console.log();
        sp.text(h + ":" + myFormat(m) + ":" + myFormat(s));
    }, 1000);
};
</script>

将此代码放在alert.show();

之后

list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position,
                                    long id) {

                String from_language = ((TextView)view).getText().toString();
                Toast.makeText(getBaseContext(), from_language, Toast.LENGTH_LONG).show();

                // CLOSE POPUP WINDOW
alert.dismiss();
            }
        });

您可以通过更改对话框的初始化顺序来执行此操作：

public void popUp(){
    final ListView promptView = new ListView(this);
    final AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
    alertDialogBuilder.setView(promptView);
    // setup a dialog window
    alertDialogBuilder.setCancelable(false)
            .setNegativeButton("Cancel",
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int id) {
                            dialog.cancel();
                        }
                    });

    // create an alert dialog
    final AlertDialog alert = alertDialogBuilder.create();

    String[] languages = {"Arabic","Bulgarian","Catalan"};

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_list_item_1, languages);
    promptView.setAdapter(adapter);

    promptView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position,
                                long id) {

            String from_language = ((TextView)view).getText().toString();
            Toast.makeText(getBaseContext(), from_language, Toast.LENGTH_LONG).show();

            // CLOSE POPUP WINDOW
            alert.dismiss();
        }
    });

    alert.show();
}
