我目前有一個自定義列表視圖,其中列表中的每個項目包含兩行文本。我想要做的是每次用戶點擊按鈕時,它會在用戶輸入的文本列表上創建一個新項目。雖然我知道如何獲取文本,但我無法將新項目添加到列表視圖,因爲我根本不知道從哪裏開始。Android - 將項目添加到按鈕上的自定義列表視圖點擊
這裏是我的代碼:
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;
}
}
}
