我正在处理此listView示例http://www.cs.sfu.ca/CourseCentral/276/bfraser/androidExampleCode/AndroidComplexListViewDemo.zip 并且我想在点击时在列表视图中显示图像
我还要显示项目名称。
public class MainActivity extends Activity {
private List<Car> myCars = new ArrayList<Car>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
populateCarList();
populateListView();
registerClickCallback();
}
private void populateCarList() {
myCars.add(new Car("Ford", 1940, R.drawable.help, "Needing work"));
myCars.add(new Car("Toyota", 1994, R.drawable.heart, "Lovable"));
myCars.add(new Car("Honda", 1999, R.drawable.fish, "Wet"));
myCars.add(new Car("Porche", 2005, R.drawable.lightning, "Fast!"));
myCars.add(new Car("Jeep", 200, R.drawable.star, "Awesome"));
myCars.add(new Car("Rust-Bucket", 2010, R.drawable.bug, "Not *very* good"));
myCars.add(new Car("Moon Lander", 1971, R.drawable.up, "Out of this world"));
}
private void populateListView() {
ArrayAdapter<Car> adapter = new MyListAdapter();
ListView list = (ListView) findViewById(R.id.carsListView);
list.setAdapter(adapter);
}
private void registerClickCallback() {
ListView list = (ListView) findViewById(R.id.carsListView);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View viewClicked,
int position, long id) {
Car clickedCar = myCars.get(position);
String message = "You clicked position " + position
+ " Which is car make " + clickedCar.getMake();
Toast.makeText(MainActivity.this, message, Toast.LENGTH_LONG).show();
}
});
}
private class MyListAdapter extends ArrayAdapter<Car> {
public MyListAdapter() {
super(MainActivity.this, R.layout.item_view, myCars);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// Make sure we have a view to work with (may have been given null)
View itemView = convertView;
if (itemView == null) {
itemView = getLayoutInflater().inflate(R.layout.item_view, parent, false);
}
// Find the car to work with.
Car currentCar = myCars.get(position);
// Fill the view
ImageView imageView = (ImageView)itemView.findViewById(R.id.item_icon);
imageView.setImageResource(currentCar.getIconID());
// Make:
TextView makeText = (TextView) itemView.findViewById(R.id.item_txtMake);
makeText.setText(currentCar.getMake());
// Year:
TextView yearText = (TextView) itemView.findViewById(R.id.item_txtYear);
yearText.setText("" + currentCar.getYear());
// Condition:
TextView condionText = (TextView) itemView.findViewById(R.id.item_txtCondition);
condionText.setText(currentCar.getCondition());
return itemView;
}
}
public class Car {
private String make;
private int year;
private int iconID;
private String condition;
public Car(String make, int year, int iconID, String condition) {
super();
this.make = make;
this.year = year;
this.iconID = iconID;
this.condition = condition;
}
public String getMake() {
return make;
}
public int getYear() {
return year;
}
public int getIconID() {
return iconID;
}
public String getCondition() {
return condition;
}
