1、不封装型

View layout = inflater.inflate(R.layout.enable_agree_dialog,(ViewGroup) findViewById(R.id.dialog));new AlertDialog.Builder(this).setTitle(title).setView(layout).setPositiveButton("关闭", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {}}).setNegativeButton("取消",new DialogInterface.OnClickListener() {public void onClick(DialogInterface dialog,int whichButton) {// 取消按钮事件}}).show();

2.封装

public class Dialog_edit extends AlertDialog implements OnClickListener {private String text = "";private EditText edit;private OnDateSetListener mCallback;private LinearLayout layout;public interface OnDateSetListener {void onDateSet(String text);}protected Dialog_edit(Context context, String title, String value,OnDateSetListener Callback) {super(context);mCallback = Callback;TextView label = new TextView(context);edit = new EditText(context);edit.setText(value);layout = new LinearLayout(context);layout.setOrientation(LinearLayout.VERTICAL);// LinearLayout.LayoutParams param =// new LinearLayout.LayoutParams(100, 40);// layout.addView(label, param);LinearLayout.LayoutParams param2 = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT,50);layout.addView(edit, param2);setView(layout);setTitle(title);setButton("确定", this);setButton2("取消", (OnClickListener) null);}@Overridepublic void onClick(DialogInterface dialog, int which) {// TODO Auto-generated method stub// Log.v("cola", "U click which=" + which);text = edit.getText().toString();if (mCallback != null)mCallback.onDateSet(text);}
}

上面的类Dialog_edit继承了AlertDialog实现了android.content.DialogInterface.OnClickListener接口。自己写了回调接口OnDateSetListener。
