public class MainActivity extends Activity {
	private Button btn1;
	ArrayListMultiChoiceID = new ArrayList();
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		final String [] nItems = {"item1","item2","item3","item4","item5","item6"};
		
		btn1 = (Button) findViewById(R.id.button1);
		btn1.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View v) {
				AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
				
				MultiChoiceID.clear();
				builder.setIcon(R.drawable.ic_launcher);
				builder.setTitle("多项选择");
				//	设置多选项
				builder.setMultiChoiceItems(nItems, 
						new boolean[]{false,false,false,false,false,false},
						new DialogInterface.OnMultiChoiceClickListener() {
					
							@Override
							public void onClick(DialogInterface arg0, int arg1, boolean arg2) {
								// TODO Auto-generated method stub
								if (arg2) {
									MultiChoiceID.add(arg1);
									String tip = "你选择的ID为"+arg1+",值为"+nItems[arg1];
									Toast toast = Toast.makeText(getApplicationContext(), tip, Toast.LENGTH_SHORT);
									toast.show();
								}
								else {
									MultiChoiceID.remove(arg1);
								}
							}
				});
				//	设置确定按钮
				builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
					
					@Override
					public void onClick(DialogInterface arg0, int arg1) {
						// TODO Auto-generated method stub
						String str = "";
						int size = MultiChoiceID.size();
						for(int i = 0; i < size; i++) {
							str += (nItems[MultiChoiceID.get(i)]+",");
						}
						Toast toast = Toast.makeText(getApplicationContext(), "你选择了"+str, Toast.LENGTH_LONG);
						toast.show();
					}
				});
				//	设置取消按钮
				builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
					
					@Override
					public void onClick(DialogInterface arg0, int arg1) {
						// TODO Auto-generated method stub
						
					}
				});
