Question

public void onItemClick(AdapterView<?> a, View v, int position, long id) {
    AlertDialog.Builder adb = new AlertDialog.Builder(CategoriesTab.this);

    adb.setTitle("Selected Category");
    adb.setMessage("Selected Item is = "+lv1.getItemAtPosition(position));
    adb.setPositiveButton("Ok", null);
    adb.show();
}

当点击listview中的项目时，此时会显示一个警告框。我想转换警报框以为每个单击的选项加载特定的xml。我怎样才能做到这一点？谢谢你的帮助。

Answer 1

switch(position) {
    case 0:
        setContentView(R.layout.xml0);
        break;
    case 1:
        setContentView(R.layout.xml1);
        break;
    default:
        setContentView(R.layout.default);
}

我希望这能做到这一点！

你的意思是？

你可以这样做：

@Override
protected Dialog onCreateDialog(int id) {
    String messageDialog;
    String valueOK;
    String valueCancel;
    String titleDialog;
    switch (id) {

    case id:
        titleDialog = itemTitle;
        messageDialog = itemDescription
        valueOK = "OK";            
        return new AlertDialog.Builder(HomeView.this).setTitle(titleDialog).setPositiveButton(valueOK, new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {
                Log.d(this.getClass().getName(), "AlertItem");
            }
        }).setMessage(messageDialog).create();

然后致电

showDialog(numbreOfItem);
