我有以下布局文件和适配器代码:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="70dip"
android:background="@drawable/white"
android:orientation="horizontal"
android:padding="10sp">
<ImageView android:id="@+id/Logo"
android:layout_width="50dip"
android:layout_height="50dip"
android:layout_alignParentTop="true"
android:layout_alignParentBottom="true"
android:layout_marginRight="6dip" />
<TextView
android:id="@+id/name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FF000000"
android:textStyle="bold"
android:textSize="12sp"
android:typeface="sans"
android:layout_toRightOf="@id/Logo" />
<TextView
android:id="@+id/description"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="12sp"
android:layout_below="@id/name"
android:textColor="#0000CC"
android:layout_toRightOf="@id/Logo" />
<TextView
android:id="@+id/address"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:textSize="12sp"
android:layout_below="@id/description"
android:textColor="#990000"
android:layout_toRightOf="@id/Logo"
/>
</RelativeLayout>
private void showPlaces(Cursor cursor) {
MyCustomAdapterClass adapter = new MyCustomAdapterClass(this,cursor, true);
setListAdapter(adapter);
}
谁能告诉我如何设置 onclick 监听器来检测某人何时单击我的列表中的项目？
谢谢!
编辑整个主要内容:
package org.example.DatabaseImport;
import java.io.IOException;
import android.app.Activity;
import android.database.SQLException;
import android.os.Bundle;
import static android.provider.BaseColumns._ID;

public class Main extends ListActivity {

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ListView yourList = (ListView) findViewById(R.id.list);
yourList.setOnItemClickListener(new OnItemClickListener() {

}
});
myDbHelper = new DataBaseHelper(this);
try {
myDbHelper.createDataBase();
} catch (IOException ioe) {
throw new Error("Unable to create database");
}
try {
myDbHelper.openDataBase();
}catch(SQLException sqle){
throw sqle;
}
try {

showPlaces(cursor);
}
finally {
myDbHelper.close();
}
}
private static String[] FROM = { _ID, AREA, ADDRESS, UNIQUEID};
private static String ORDER_BY = _ID + " ASC";
private Cursor getPlaces() {
SQLiteDatabase db = myDbHelper.getReadableDatabase();
Cursor cursor = db.query(TABLE_NAME, null, null, null, null, null, ORDER_BY);
startManagingCursor(cursor);
return cursor;
}
private static int[] TO = {R.id.name, R.id.description, R.id.address, };
private void showPlaces(Cursor cursor) {
MyCustomAdapterClass adapter = new MyCustomAdapterClass(this,cursor, true); setListAdapter(adapter);
}
这是 main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ListView
android:id="@android:id/list"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
最佳答案
public class Main extends ListActivity implements OnItemClickListener {
private DataBaseHelper myDbHelper;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
myDbHelper = new DataBaseHelper(this);
try {
myDbHelper.createDataBase();
} catch (IOException ioe) {
throw new Error("Unable to create database");
}
try {
myDbHelper.openDataBase();
}catch(SQLException sqle){
throw sqle;
}
try {
Cursor cursor = getPlaces();
showPlaces(cursor);
}
finally {
myDbHelper.close();
}
}
private static String[] FROM = { _ID, AREA, ADDRESS, UNIQUEID};
private static String ORDER_BY = _ID + " ASC";
private Cursor getPlaces() {
SQLiteDatabase db = myDbHelper.getReadableDatabase();
Cursor cursor = db.query(TABLE_NAME, null, null, null, null, null, ORDER_BY);
startManagingCursor(cursor);
return cursor;
}
private static int[] TO = {R.id.name, R.id.description, R.id.address, };
private void showPlaces(Cursor cursor) {
MyCustomAdapterClass adapter = new MyCustomAdapterClass(this,cursor, true); setListAdapter(adapter);
}
@Override
public void onItemClick(AdapterView<?> arg0, View v, int position, long arg3) {
Log.e("Position",""+position);
}
关于java - 为适配器 View 设置 Onclick 监听器，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/7316955/
