我正在android studio中搜索一个简单的列表视图。我创建了这个类： Success.java
public class Success extends Activity {
protected String[] plates = {"AA 367 AM", "AA 367 AL","AA 367 AK"};
protected ListAdapter adapter;
private ListView myListView;
EditText inputSearch;
ArrayAdapter<String> myAdapter;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.success);
inputSearch = (EditText) findViewById (R.id.searchText);
myListView = (ListView) findViewById (R.id.list);
myAdapter = new ArrayAdapter<String>(this, R.layout.plates, R.id.plate_name, plates);
myListView.setAdapter(myAdapter);
myListView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
String item = ((TextView)view).getText().toString();
Intent intent = new Intent(Success.this,Info.class);
intent.putExtra("Plate",item);
startActivity(intent);
}
});
inputSearch.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
Success.this.myAdapter.getFilter().filter(cs);
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
}
@Override
public void afterTextChanged(Editable arg0) {
}
});
}
}
和success.xml
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<Button
android:id="@+id/searchButton"
android:text="Search"
android:layout_width="110dp"
android:layout_height="wrap_content"
android:layout_gravity="right" />
<EditText
android:id="@+id/searchText"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
<ListView android:id="@+id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:drawSelectorOnTop="false"
android:scrollbars="vertical"/>
</LinearLayout>
搜索有效但项目点击显示不幸的是，program2已停止 Info.java
public class Info extends Activity {
ImageView imageView2;
ImageView imageView3;
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_info);
imageView2=(ImageView)findViewById(R.id.imageView2);
imageView3=(ImageView)findViewById(R.id.imageView3);
TextView tv3 = (TextView) findViewById(R.id.intent3);
String plate = getIntent().getExtras().getString("Plate");
tv3.setText(""+getIntent().getExtras().getString("Plate"));
imageView2.setImageResource(R.drawable.car1);
imageView3.setImageResource(R.drawable.status1);
}
}
