android的artdialog的用法

作了個小程序，最後沒有用上，但用法是徹底體現出來了：

我定義了幾個按鈕的,代碼很清晰，沒有必要贅述了。

protected void initFilterbar(){

id_cat=(Button)findViewById(R.id.id_cat);

id_year=(Button)findViewById(R.id.id_year);

id_order=(Button)findViewById(R.id.id_order);

id_cat.setOnClickListener(filter_click);

id_year.setOnClickListener(filter_click);

id_order.setOnClickListener(filter_click);

}

protected View.OnClickListener filter_click=new View.OnClickListener() {

@Override

public void onClick(View v) {

switch(v.getId())

{

case R.id.id_cat:{

showDialogPopup(R.id.id_cat);

break;

}

case R.id.id_year:{

showDialogPopup(R.id.id_year);

break;

}

case R.id.id_order:{

showDialogPopup(R.id.id_cat);

break;

}

}

}

};

protected void showDialogPopup(int viewId)

{

AlertDialog.Builder localBuilder = new AlertDialog.Builder(this);

switch(viewId)

{

case R.id.id_cat:{

//設置adpter

if(catadpter == null){

catadpter = new CatAdapter(this);

}

localBuilder.setAdapter(catadpter, new flPopupListener(catadpter)); 

break;

}

case R.id.id_year:{

break;

}

case R.id.id_order:{

break;

}

}

AlertDialog localAlertDialog = localBuilder.create();

localAlertDialog.show();

}

class flPopupListener implements DialogInterface.OnClickListener{

CatAdapter catadpter;

public flPopupListener(ListAdapter catadpter)

{

catadpter = (CatAdapter)catadpter;

}
