[android]代码库

		myListView = new ListView(this);
		LinearLayout.LayoutParams param2 = new LinearLayout.LayoutParams(
				LinearLayout.LayoutParams.FILL_PARENT,
				LinearLayout.LayoutParams.WRAP_CONTENT);
		myListView.setBackgroundColor(getResources()
				.getColor(R.drawable.ltgray));
		/* 将ListView加到myLinearLayout */
		myLinearLayout.addView(myListView, param2);
		/* 将LinearLayout加到ContentView */
		setContentView(myLinearLayout);
		/* new ArrayAdapter对象并将array字符串数组传入 */
		ArrayAdapter adapter = new ArrayAdapter(this,
				R.layout.my_simple_list_item, array);
		/* 将ArrayAdapter加入ListView对象中 */
		myListView.setAdapter(adapter);
		/* myListView加入OnItemSelectedListener */
		myListView
				.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
					@Override
					public void onItemSelected(AdapterView arg0, View arg1,
							int arg2, long arg3) {
						/* 使用getSelectedItem()将选取的值带入myTextView中 */
						myTextView.setText("你选的是"
								+ arg0.getSelectedItem().toString());
					}

					@Override
					public void onNothingSelected(AdapterView arg0) {
						// TODO Auto-generated method stub
					}
				});
		/* myListView加入OnItemClickListener */
		myListView
				.setOnItemClickListener(new AdapterView.OnItemClickListener() {
					@Override
					public void onItemClick(AdapterView arg0, View arg1,
							int arg2, long arg3) {
						/*
						 * 使用String[index]，arg2为点选到ListView的index，并将值带入myTextView中
						 */
						myTextView.setText("你选的是" + array[arg2]);
					}
				});
