本文介绍了一种在Android中使用AlertDialog时，通过自定义视图布局来改善动态添加组件显示效果的方法。通过对视图进行特定设置，使得组件在弹窗内不再紧贴边框，提升了用户体验。

先上图

AlertDialog有个问题是动态添加组件时，组件会很靠边框，这样很不好看，下面这个方案是解决这个问题

		LayoutInflater mInflater = (LayoutInflater) getContext()
				.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
		View view = mInflater.inflate(R.layout.recordlayout, null);
		LinearLayout layout = (LinearLayout) view
				.findViewById(R.id.id_recordlayout);
		for (int i = 0; i < fieldName.length; i++) {
			String name = fieldName[i];
			if ("_id".equals(name))
				continue;
			TextView tv = new TextView(getContext());
			tv.setText(fieldName[i]);
			EditText edit = new EditText(getContext());
			layout.addView(tv);
			layout.addView(edit);
		}

		AlertDialog.Builder dialog = new AlertDialog.Builder(getContext());
		dialog.setTitle(R.string.add_a_record);
		dialog.setView(view);

		dialog.setPositiveButton(R.string.ok,
				new DialogInterface.OnClickListener() {
					public void onClick(DialogInterface dialog, int which) {

					}
				});
		dialog.setNegativeButton(R.string.cancel,
				new DialogInterface.OnClickListener() {
					public void onClick(DialogInterface dialog, int which) {

					}
				});
		dialog.show();
