我正在做一个必须显示标题和说明的项目。但问题是描述中的文字有点冗长，当我们点击标记时没有显示。我想要显示完整描述的片段大小，否则需要一些其他选项？

答案 0 :(得分：0)
您可以添加自定义弹出窗口而不是片段，类似这样，
private void showPopup(final Activity context, String address) {
LinearLayout viewGroup = (LinearLayout) context.findViewById(R.id.popup);
LayoutInflater layoutInflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = layoutInflater.inflate(R.layout.pop_up_layout, viewGroup);
TextView textView = (TextView) layout.findViewById(R.id.txt_address);
textView.setText(address);
// Creating the PopupWindow
final PopupWindow popup = new PopupWindow(context);
popup.setContentView(layout);
popup.setWidth(LinearLayout.LayoutParams.WRAP_CONTENT);
popup.setHeight(LinearLayout.LayoutParams.WRAP_CONTENT);
popup.setFocusable(true);
// Clear the default translucent background
popup.setBackgroundDrawable(new BitmapDrawable());
// Displaying the popup at the specified location, + offsets.
popup.showAtLocation(layout, Gravity.NO_GRAVITY, mPoint.x, mPoint.y + 50 );
}
