我有我的列表視圖的問題。當在edittext中輸入文本時，edittext（我在其中輸入）的焦點會轉到listview中的另一個編輯文本。另外當我滾動我的列表視圖的最上面的edittext的值下降到屏幕上可見的最後一個編輯文本。幫我解決這個問題。滾動列表視圖時，編輯文本值變爲空或向上
我single_row.xml代碼：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ffffff" >
<TextView
android:id="@+id/textViewSingleRowAddEditCategory"
android:layout_width="250dp"
android:layout_marginTop="10dp"
android:layout_height="wrap_content"
style="@style/font_color_and_type"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:text="TextView" />
<EditText
android:id="@+id/editTextSingleRowAddEditCategory"
android:layout_width="250dp"
android:layout_height="40dp"
android:layout_below="@+id/textViewSingleRowAddEditCategory"
android:layout_centerHorizontal="true" >
</EditText>
<ImageView
android:id="@+id/imageViewAddEditCategoryEraseData"
android:layout_width="35dp"
android:layout_height="35dp"
android:layout_alignTop="@+id/editTextSingleRowAddEditCategory"
android:layout_toRightOf="@+id/editTextSingleRowAddEditCategory"
android:src="@drawable/delete4" />
</RelativeLayout>
我main_layout.xml代碼：下面
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff"
tools:context=".AddEditCategory" >
<RelativeLayout
android:id="@+id/relativeLayoutAddEditCategoryTopBar"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" >
<TextView
android:id="@+id/textViewAddEditScreenTitle"
android:text="Screen Title"
style="@style/screen_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<ImageView
android:id="@+id/imageViewAddEditCategoryDelete"
android:layout_width="22dp"
android:layout_height="22dp"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="24dp"
android:src="@drawable/set_delete" />
</RelativeLayout>
<View
android:id="@+id/view5"
android:layout_width="match_parent"
android:layout_height="5dp"
android:layout_below="@+id/relativeLayoutAddEditCategoryTopBar"
android:background="@drawable/shadow" />
<ListView
android:id="@+id/listViewAddEditCategory"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@+id/view5"
android:divider="@android:color/transparent"
android:dividerHeight="1dp" >
</ListView>
<Button
android:id="@+id/buttonAddEditCategorySave"
android:layout_width="250dp"
android:layout_height="40dp"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:text="Save" />
</RelativeLayout>
Main_activity.java的代碼給出：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_add_edit_category);
this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
Intent intent = getIntent();
final String operation = intent.getStringExtra("operation");
tv_screen_title = (TextView) findViewById(R.id.textViewAddEditScreenTitle);
tv_screen_title.setText(operation);
iv_delete = (ImageView) findViewById(R.id.imageViewAddEditCategoryDelete);
al_items_from_editText = new ArrayList<String>();
btn_save = (Button) findViewById(R.id.buttonAddEditCategorySave);
btn_save.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if (operation.equals("Add Category")) {
loadDatabase();
View view1 = listview_add_edit_category.getChildAt(0);
EditText et = (EditText) view1
.findViewById(R.id.editTextSingleRowAddEditCategory);
String category_name = et.getText() + "";
Log.i("category_name", category_name);
for (int i = 1; i < listview_add_edit_category
.getChildCount(); i++) {
View view = listview_add_edit_category.getChildAt(i);
EditText editText = (EditText) view
.findViewById(R.id.editTextSingleRowAddEditCategory);
al_items_from_editText.add(editText.getText()+"");
Log.i(i+"", editText.getText()+"");
}
}
});
listview_add_edit_category = (ListView) findViewById(R.id.listViewAddEditCategory);
if (operation.equals("Add Category")) {
iv_delete.setVisibility(View.GONE);
manageAddCategoryList();
mPLAdapter = new PlacesListAdapter(AddEditCategory.this,
mPlacesData1, mPlacesData2);
listview_add_edit_category.setAdapter(mPLAdapter);
}
}
private void manageAddCategoryList() {
mPlacesData1.clear();
mPlacesData2.clear();
mPlacesData1.add("Category Name");
mPlacesData2.add("Name");
mPlacesData1.add("# Field 1");
mPlacesData2.add("Field 1");
mPlacesData1.add("# Field 2");
mPlacesData2.add("Field 2");
mPlacesData1.add("# Field 3");
mPlacesData2.add("Field 3");
mPlacesData1.add("# Field 4");
mPlacesData2.add("Field 4");
mPlacesData1.add("# Field 5");
mPlacesData2.add("Field 5");
mPlacesData1.add("# Field 6");
mPlacesData2.add("Field 6");
mPlacesData1.add("# Field 7");
mPlacesData2.add("Field 7");
mPlacesData1.add("# Field 8");
mPlacesData2.add("Field 8");
mPlacesData1.add("# Field 9");
mPlacesData2.add("Field 9");
mPlacesData1.add("# Field 10");
mPlacesData2.add("Field 10");
}
private void loadDatabase() {
database = openOrCreateDatabase(database_name,
SQLiteDatabase.OPEN_READWRITE, null);
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0) {
finish();
startActivity(new Intent(AddEditCategory.this,
CategoryManagement.class));
return true;
}
return super.onKeyDown(keyCode, event);
}
而且這個PlaceListAdapter .java代碼：
package com.walletapp;
import java.util.ArrayList;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.TextView;
public class PlacesListAdapter extends BaseAdapter {
// private Context mContext;
private LayoutInflater mInflater;
private ArrayList<String> al_caption = new ArrayList<String>();
private ArrayList<String> al_hint = new ArrayList<String>();
public PlacesListAdapter(Context c, ArrayList<String> al_caption,
ArrayList<String> al_hint) {
mInflater = LayoutInflater.from(c);
// mContext = c;
this.al_caption = al_caption;
this.al_hint = al_hint;
}
public int getCount() {
return al_caption.size();
}
public Object getItem(int position) {
return al_caption.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(final int position, View convertView, ViewGroup parent) {
final ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(
R.layout.single_row_add_edit_category, null);
holder = new ViewHolder();
holder.tv_caption = (TextView) convertView
.findViewById(R.id.textViewSingleRowAddEditCategory);
holder.et_value = (EditText) convertView
.findViewById(R.id.editTextSingleRowAddEditCategory);
holder.erase_data = (ImageView) convertView
.findViewById(R.id.imageViewAddEditCategoryEraseData);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.tv_caption.setText(al_caption.get(position));
holder.et_value.setHint(al_hint.get(position));
holder.erase_data.setVisibility(View.GONE);
return convertView;
}
static class ViewHolder {
TextView tv_caption;
EditText et_value;
ImageView erase_data;
}
}
請幫助我的人。
都都在您的ListView中的EditText項目可見，還是有不可見的物品？第二個問題是由適配器中的回收造成的。 – Neil 2013-03-11 07:11:48
@Neil no ...我沒有設置任何視圖在列表視圖中不可見，事實上，我在另一種情況下以編程方式隱形，因爲我使用相同的活動和xml來完成兩個不同的任務。 – 2013-03-11 07:17:07
