[英]Listview OnItemClickListener() for custom layout
I have my listview with custom layout 我的列表视图具有自定义布局
custom_layout.xml custom_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:stretchColumns="1" >
<TableRow>
<TextView
android:id="@+id/item1"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:padding="10dip"
android:textColor="@color/white_color"
android:layout_margin="4dip"
android:layout_weight="0.15"
/>
<TextView
android:id="@+id/item2"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:padding="10dip"
android:textColor="@color/white_color"
android:layout_margin="4dip"
android:layout_weight="0.53"
/>
<TextView
android:id="@+id/item3"
android:layout_width="0dip"
android:layout_height="match_parent"
android:layout_gravity="right"
android:gravity="right"
android:padding="10dip"
android:textColor="@color/white_color"
android:layout_margin="4dip"
android:layout_weight="0.32"
/>
</TableRow>
Listview with arrayadapter: 具有arrayadapter的Listview:
ListView lv = (ListView) findViewById(R.id.prodlist);
String[] from = new String[] { "rowid", "col_1", "col_2" };
int[] to = new int[] { R.id.item1, R.id.item2, R.id.item3 };
// prepare the list of all records
ArrayList<HashMap<String, String>> fillMaps = new ArrayList<HashMap<String, String>>();
for (int i = 0; i < 20; i++) {
HashMap<String, String> map = new HashMap<String, String>();
map.put("rowid", "" + i);
map.put("col_1", name);
map.put("col_2", qnt);
}
fillMaps.add(map);
SimpleAdapter adapter = new SimpleAdapter(this, fillMaps, R.layout.custom_layout, from, to);
lv.setAdapter(adapter);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//How to get item2 text value?..
}
});
All three textview are added in the arrayadapter.All I want to do is when I click the listview,how to get the text of textview(r.id.item2). 这三个textview都添加到arrayadapter中。我要做的就是单击列表视图时如何获取textview(r.id.item2)的文本。
Inside your onItemClick
: 在您的
onItemClick
内部:
HashMap<String, String> hashReference = (HashMap)parent.getItemAtPosition(position);
String name = hashReference.get("col_1"); //the keys that you saved above.
String qnt = hashReference.get("col_2");
You can use View view
argument of your onItemClick()
of ListView
, 您可以使用
ListView
onItemClick()
的View view
参数,
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,int position, long id) {
TextView mTextView = (TextView)view.findViewById(r.id.item2);
String value = mTextView.getText().toString();
}
});
String item1= ((TextView) view.findViewById(R.id.item1)).getText().toString();
String item2= ((TextView) view.findViewById(R.id.item2)).getText().toString();
String item3= ((TextView) view.findViewById(R.id.item3)).getText().toString();
You can get HashMap
from the list by using position
of clicked item. 您可以通过使用单击项的
position
从列表中获取HashMap
。
Like below 像下面
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,int position, long id) {
//How to get item2 text value?..
HashMap<String, String> map = fillMaps.get(position);
String col1Value = map.get("col_1");
String col2Value = map.get("col_2");
}
});
// try this way
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String item1 = fillMaps.get(position).get("rowid");
String item2 = fillMaps.get(position).get("col_1");
String item3 = fillMaps.get(position).get("col_2");
}
});
