public class TestActivity extends Activity {  /**代码中写布局的View*/  private LinearLayout mParentLinearLayout;  /**标题TextView*/  private TextView mTitleTv;  /**展示数据的ListView*/  private ListView mListView;  /**自定义的数据*/  private String[] mStrArray;  /**ListView的数据适配器*/  private ArrayAdapter<String> arrayAdapter;  /**定义一StringBuffer*/  private StringBuffer mBuffer;      @Override  public void onCreate(Bundle savedInstanceState) {  super.onCreate(savedInstanceState);  initViews();  initListeners();  }    private void initListeners() {  mListView.setOnItemSelectedListener(mLvOnItemSelectedListener);  mListView.setOnItemClickListener(mLvOnItemClickListener);  }    private void initViews() {  /**初始化mParentLinearLayout*/  mParentLinearLayout = new LinearLayout(TestActivity.this);  /**设置布局宽高*/  LinearLayout.LayoutParams mLayoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);  /**布局排列方式*/  mParentLinearLayout.setOrientation(LinearLayout.VERTICAL);  /**背景*/  mParentLinearLayout.setBackgroundColor(Color.parseColor("#F0F0F0"));      mTitleTv = new TextView(TestActivity.this);  mTitleTv.setLayoutParams(mLayoutParams);  mTitleTv.setText("请选择列表数据!");  mTitleTv.setTextColor(Color.BLACK);  /**往布局中添加TextView*/  mParentLinearLayout.addView(mTitleTv);      mListView = new ListView(TestActivity.this);  mListView.setLayoutParams(mLayoutParams);  mListView.setBackgroundColor(Color.LTGRAY);  mBuffer = new StringBuffer();  mStrArray = new String[] { "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" };  arrayAdapter = new ArrayAdapter<String>(TestActivity.this, android.R.layout.simple_list_item_multiple_choice, mStrArray);  /**设置ListView的选择模式*/  mListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);  mListView.setAdapter(arrayAdapter);  /**往布局中添加ListView*/  mParentLinearLayout.addView(mListView);  setContentView(mParentLinearLayout);  }      private OnItemSelectedListener mLvOnItemSelectedListener = new OnItemSelectedListener() {      public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {  /**选中后的操作*/  mBuffer.append(arg0.getItemAtPosition(arg2).toString() + "-");  mTitleTv.setText(mBuffer.toString());  }    public void onNothingSelected(AdapterView<?> arg0) {    }  };  OnItemClickListener mLvOnItemClickListener = new OnItemClickListener() {    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {  /**点击后的操作*/  mBuffer.append(arg0.getItemAtPosition(arg2).toString() + "");  mTitleTv.setText(mBuffer.toString());  /**还可以判断,如果已经选中,点击的话应该表示不选中*/  }  };  }
