java - Android获取文本EditText到AlertDialog

Question

我必须从 AlertDialog 中获取文本。

对于 AlertDialog，我使用特定的布局:custom_alertdialog

对于所有项目使用:另一个布局

我尝试过这样的:

View layout = getLayoutInflater().Inflate(R.layout.custom_alertdialog,null);

或者这样:

View layout = View.inflate(SimpleVideoStream.this, R.layout.custom_alertdialog, null);

但是在这两种情况下都不会采用文本。我该怎么办？

AlertDialog.Builder builder = new AlertDialog.Builder(SimpleVideoStream.this);
        builder.setTitle("Add Subtitle");
        builder.setCancelable(true);

        builder.setPositiveButton(
                "Ok",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        View inflatedView = getLayoutInflater().inflate(R.layout.custom_alertdialog, null);
                        final View layout = View.inflate(SimpleVideoStream.this, R.layout.custom_alertdialog, null);

                        EditText url_ele = (EditText) layout.findViewById(R.id.url);
                        String sub = url_ele.getText().toString();
                        Log.v("Ok:","/"+sub);
                        if (!sub.equals("")) {
                            showSub = !showSub;
                            Format textFormat = Format.createTextSampleFormat(null, MimeTypes.APPLICATION_SUBRIP,
                                    null, Format.NO_VALUE, Format.NO_VALUE, "en", null, Format.OFFSET_SAMPLE_RELATIVE);
                            MediaSource textMediaSource = new SingleSampleMediaSource.Factory(dataSourceFactory)
                                    .createMediaSource(Uri.parse(sub), textFormat, C.TIME_UNSET);

                            videoSource = new MergingMediaSource(videoSource, textMediaSource);
                            player.prepare(videoSource, false, false);
                        }
                        dialog.cancel();
                    }
                });

        builder.setNegativeButton(
                "Close",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        dialog.cancel();
                    }
                });

        AlertDialog alert = builder.create();
        LayoutInflater inflater = getLayoutInflater();
        View dialoglayout = inflater.inflate(R.layout.custom_alertdialog, null);
        alert.setView(dialoglayout);
        alert.show();

在您的 builder 实例中，您膨胀了一个布局(布局 A)。在 setView() 方法之前，您膨胀了另一个布局(布局B)。这两种布局是不同的。

你可以这样做:

AlertDialog.Builder builder = new AlertDialog.Builder(SimpleVideoStream.this);
LayoutInflater inflater = this.getLayoutInflater();
View dialogView= inflater.inflate(R.layout.custom_alertdialog, null); 
builder.setView(inflater.inflate(R.layout.custom_alertdialog, null))
final EditText editText = (EditText)dialogView.findViewById(R.id.url); 

builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int id) {
                     //Do something
                    }
                }
            });
       .setNegativeButton(){
                   //Do something
       };
builder.create();
builder.show();
