Question

我目前正在尝试使用自定义布局文件“details.xml”弹出一个AlertDialog框，其中包含有关电影的信息。我觉得这可能就是我如何使用AlertDialog来填充这些字段，但我不确定如何最好地处理它。

listView.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> Parent, View view, int position,
                long id) {
            // TODO Auto-generated method stub
            Movie mTemp = movieArray.get(position);             
            //Intent intent = new Intent(getApplicationContext(), SingleItemList.class);

            AlertDialog.Builder builder = new AlertDialog.Builder(MovieList.this);
            builder.setView(getLayoutInflater().inflate(R.layout.details, null));
            builder.setTitle("Details");
            builder.setNeutralButton("Post to Facebook", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    // User clicked OK button
                }
            });
            AlertDialog d = builder.create();
            if (mTemp != null) {
                ImageView image = (ImageView) d.findViewById(R.id.detailIcon);
                TextView title = (TextView) d.findViewById(R.id.detailTitle);
                TextView year = (TextView) d.findViewById(R.id.detailYear);
                TextView rating = (TextView) d.findViewById(R.id.detailRating);
                TextView director = (TextView) d.findViewById(R.id.detailDirector);

                if (title != null) {
                    title.setText("Name: " + mTemp.title);
                }

                if(year != null) {
                    year.setText("Year: " + mTemp.year);
                }

                if(rating != null) {
                    rating.setText("Rating: " + mTemp.rating + "/10");
                }

                if(director != null) {
                    director.setText("Director: " + mTemp.director);
                }

                if(image != null) {
                    image.setImageBitmap(getBitmap(mTemp.coverURL));
                }
            }

            d.show();

            /*
            Dialog dialog = new Dialog(MovieList.this);
            dialog.setTitle("Details");
            dialog.setContentView(R.layout.details);


            dialog.show();*/
        }
});

您尚未发布LogCat错误，但我认为是(mTemp != null)阻止导致问题的阻止。更改膨胀的视图，然后将其传递给setView()。

View view = getLayoutInflater().inflate(R.layout.details, null);
if (mTemp != null) {
    ImageView image = (ImageView) view.findViewById(R.id.detailIcon);
    TextView title = (TextView) view.findViewById(R.id.detailTitle);
    ...
}

AlertDialog.Builder builder = new AlertDialog.Builder(MovieList.this);
builder.setTitle("Details");
builder.setView(view);
builder.setNeutralButton("Post to Facebook", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int id) {
                // User clicked OK button
            }
        });

AlertDialog d = builder.create();
d.show();

必须在添加内容之前调用RequestFeature，不确定为什么要调用它
