【问题描述】：
我有一个列表视图，其中包含在我单击每个项目时启动的相应活动。它工作正常。但是当我搜索“Pedro”并单击它时，不要启动正确的活动。它打开了第一个活动“Joao.class”
这是我的代码。拜托，我需要一个详细的解释。我不太了解Java，所以有人可以向我解释或告诉我应该在哪里更改代码？
非常感谢！！！
public class Main extends Activity {
private ListView lv1;
private EditText ed;
private String lv_arr[]= {"Android","Cupcake","Donut","Eclairs","AndroidPeople","Froyo",};
private ArrayList<String> arr_sort= new ArrayList<String>();
int textlength=0;
@Override
public void onCreate(Bundle icicle)
{
super.onCreate(icicle);
setContentView(R.layout.main);
lv1=(ListView)findViewById(R.id.ListView01);
ed=(EditText)findViewById(R.id.EditText01);
lv1.setOnItemClickListener(new OnItemClickListener(){
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long arg3) {
if ("João".equals(lv_arr[position])) {
Intent myIntent = new Intent(Main.this, Joao.class);
startActivity(myIntent);
}
if ("Maria".equals(lv_arr[position])) {
Intent myIntent = new Intent(Main.this, Maria.class);
startActivity(myIntent);
}
if ("Pedro".equals(lv_arr[position])) {
Intent myIntent = new Intent(Main.this, Pedro.class);
startActivity(myIntent);
}
}
});
// By using setAdpater method in listview we an add string array in list.
lv1.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1 , lv_arr));
ed.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {
}
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
public void onTextChanged(CharSequence s, int start, int before,
int count) {
textlength=ed.getText().length();
arr_sort.clear();
for(int i=0;i<lv_arr.length;i++)
{
if(textlength<=lv_arr[i].length())
{
if(ed.getText().toString().equalsIgnoreCase((String) lv_arr[i].subSequence(0, textlength)))
{
arr_sort.add(lv_arr[i]);
}
}
}
lv1.setAdapter(new ArrayAdapter<String>(Main.this,android.R.layout.simple_list_item_1 , arr_sort));
}
});
}
}
