</LinearLayout>
3. MainActivity.java
package com.example.listviewdialog;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ListView;
public class MainActivity extends Activity implements OnClickListener{
private static final String TAG = "hong";
private Button mBtnListDialog;
private ListViewDialog mDialog;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
findViews();
}
private void findViews() {
mBtnListDialog = (Button)findViewById(R.id.btn_list_dialog);
mBtnListDialog.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btn_list_dialog:
Log.d(TAG, "click button list dialg...");
showListDialog();
break;
default:
break;
}
}
private void showListDialog() {
String[] item = getResources().getStringArray(R.array.list_dialog_list_item);
//array를 ArrayList로 변경하는 방법
List<String> listitem = Arrays.asList(item);
ArrayList<String> itemArrayList = new ArrayList<String>(listitem);
mDialog = new ListViewDialog(this, getString(R.string.list_dialog_title), itemArrayList);
mDialog.onOnSetItemClickListener(new ListViewDialogSelectListener() {
@Override
public void onSetOnItemClickListener(int position) {
if(position == 0){
Log.d(TAG, "first index selected");
}
mDialog.dismiss();
}
});
mDialog.show();
}
}
DB에서 값을 받아 ArrayList에 저장 한 후 showListDialog를 호출하면서 넘겨주는 방법으로 itemArrayList를 구성할 수 도 있다. 그렇게 되면
String[] item = getResources().getStringArray(R.array.list_dialog_list_item);
List<String> listitem = Arrays.asList(item);
이 두줄의 코드는 없어져도 된다.
4. ListViewDialog.java
package com.example.listviewdialog;
import java.util.ArrayList;
import android.app.Dialog;
import android.content.Context;
import android.util.Log;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
public class ListViewDialog extends Dialog{
private static final String TAG = "hong";
private ListViewDialogSelectListener mListener;
private Context mContext;
private ArrayList<String> mStrListItem;
private ListView mListView;
public ListViewDialog(Context context, String title, ArrayList<String> item) {
super(context);
setContentView(R.layout.list_view_dialog);
mContext = context;
findViews();
setTitle(title);
mStrListItem = item;
createListViewDialog();
}
private void createListViewDialog() {
ArrayAdapter<String> adapter = new ArrayAdapter<String>(mContext, android.R.layout.simple_list_item_1, mStrListItem);
mListView.setAdapter(adapter);
mListView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
Log.d(TAG, "list index = [" + arg2 + "]");
mListener.onSetOnItemClickListener(arg2);
}
});
}
private void findViews() {
mListView = (ListView) findViewById(R.id.list_view_dialog);
}
public void onOnSetItemClickListener(ListViewDialogSelectListener listener) {
mListener = listener;
}
}
5. ListViewDialogSelectListener.java
package com.example.listviewdialog;
public interface ListViewDialogSelectListener {
public void onSetOnItemClickListener(int position);
}
