android 往dialog中加入listview，并实现listview中item的点击事件

Posted 2021-02-07 skiwnchhw

		LinearLayout linearLayoutMain = new LinearLayout(this);//自定义一个布局文件
		linearLayoutMain.setLayoutParams(new LayoutParams(
				LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
		ListView listView = new ListView(this);//this为获取当前的上下文
		listView.setFadingEdgeLength(0);

		List<Map<String, String>> nameList = new ArrayList<Map<String, String>>();//建立一个数组存储listview上显示的数据
		for (int m = 0; m < initData.size(); m++) {//initData为一个list类型的数据源
			Map<String, String> nameMap = new HashMap<String, String>();
			nameMap.put("name", initData.get(m).get(TagItem.NAME).toString());
			nameList.add(nameMap);
		}

		SimpleAdapter adapter = new SimpleAdapter(UploadPhotoActivity.this,
				nameList, R.layout.item_uploadphoto_select_name,
				new String[] { "name" },
				new int[] { R.id.tv_uploadphoto_select_name_item });
		listView.setAdapter(adapter);

		linearLayoutMain.addView(listView);//往这个布局中加入listview

		final AlertDialog dialog = new AlertDialog.Builder(this)
				.setTitle("选择患者姓名").setView(linearLayoutMain)//在这里把写好的这个listview的布局加载dialog中
				.setNegativeButton("取消", new DialogInterface.OnClickListener() {

					@Override
					public void onClick(DialogInterface dialog, int which) {
						// TODO Auto-generated method stub
						dialog.cancel();
					}
				}).create();
		dialog.setCanceledOnTouchOutside(false);//使除了dialog以外的地方不能被点击
		dialog.show();
		listView.setOnItemClickListener(new OnItemClickListener() {//响应listview中的item的点击事件

			@Override
			public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
					long arg3) {
				// TODO Auto-generated method stub
				TextView tv = (TextView) arg1
						.findViewById(R.id.tv_uploadphoto_select_name_item);//取得每条item中的textview控件
				et_name.setText(tv.getText().toString());
				dialog.cancel();
			}
		});
