我目前有一个自定义列表视图，其中列表中的每个项目包含两行文本。我想要做的是每次用户点击按钮时，它会在用户输入的文本列表上创建一个新项目。虽然我知道如何获取文本，但我无法将新项目添加到列表视图，因为我根本不知道从哪里开始。Android - 将项目添加到按钮上的自定义列表视图点击
这里是我的代码：
public class MainFeedActivity extends ListActivity implements OnClickListener {
View sendButton;
EditText postTextField;
TextView currentTimeTextView, mainPostTextView;
ListView feedListView;
String[] test;
ArrayList<HashMap<String, String>> list;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_feed);
//create button and implement on click listener
sendButton = this.findViewById(R.id.sendPostButton);
sendButton.setOnClickListener(this);
list = new ArrayList<HashMap<String, String>>();
//create the adapter for the list view
SimpleAdapter adapter = new SimpleAdapter(
this,
list,
R.layout.post_layout,
new String[]{"time", "post"},
new int[]{R.id.postTimeTextView, R.id.postTextView});
//fill the list view with something - TEST
fillData();
//set list adapter
setListAdapter(adapter);
}
public void fillData() {
//long timeTest = System.currentTimeMillis();
HashMap<String, String> temp = new HashMap<String, String>();
temp.put("time", "current time");
temp.put("post", "USER TEXT GOES HERE");
list.add(temp);
}
@Override
public void onClick(View button) {
switch (button.getId()) {
case R.id.sendPostButton:
break;
}
}
}
