动态生成UI 数据列表项(处理数据上报)1
?
核心思路：ScrollView+LinearLayout
?为什么不采用自定义Listview：
存在一些暂时未解决的问题，比较麻烦：
1.屏幕内容滚动时会调用ListView的Adapter的getView()重新产生View，这就要求及时保存EditText中的数据，不然会丢失，使用了Listener监听EditText的TextChange，但是发现Listener经常不被调用，跟踪发现在getView()中创建的Edittext和ListView中用来显示的EditText句柄不一样 。
2.再次就是当软键盘弹出后，焦点从当前输入的EditText丢失，移动了第一个EditText上，屏幕直接来个大滚屏。。。根本没法使用。

核心代码：

// 代码生成控件方法private LinearLayout newView(String category, String format, int id) {LinearLayout linearLayout = new LinearLayout(this);linearLayout.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));linearLayout.setOrientation(LinearLayout.HORIZONTAL);linearLayout.setGravity(Gravity.CENTER);// 类别TextView category_txt = new TextView(this);// 创建TextextViewiew// category_txt.setPadding(10, 0, 0, 0);category_txt.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT, 1));category_txt.setText(category); // 设置TextextViewiew显示的内容// category_txt.setWidth(100);category_txt.setSingleLine();category_txt.setTextSize(17);category_txt.setGravity(Gravity.CENTER);linearLayout.addView(category_txt);// 将textView添加到线性布局中// 规格TextView format_txt = new TextView(this);// 创建TextextViewiew// format_txt.setPadding(10, 0, 0, 0);format_txt.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT, 1));format_txt.setText(format); // 设置TextextViewiew显示的内容format_txt.setTextSize(17);format_txt.setGravity(Gravity.CENTER);// format_txt.setWidth(50);linearLayout.addView(format_txt);// 将textView添加到线性布局中// 价格EditText price_editText = new EditText(this);// price_editText.setPadding(10, 0, 0, 0);price_editText.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT, 1));price_editText.setGravity(Gravity.LEFT);price_editText.setHeight(10);price_editText.setWidth(10);// price_editText.setWidth(80);price_editText.setSingleLine();price_editText.setTextSize(17);// price_editText.setText(String.valueOf(id));// 设置测试价格数据// price_editText.setInputType(0);linearLayout.addView(price_editText);// 将textView添加到线性布局中return linearLayout;}?

private LinearLayout newView(String category, String format, int id) {LinearLayout linearLayout = new LinearLayout(this);// linearLayout.setId(id);linearLayout.setLayoutParams(params_wrapcontent);linearLayout.setOrientation(LinearLayout.HORIZONTAL);linearLayout.setGravity(Gravity.CENTER);// 类别TextView category_txt = new TextView(this);// 创建TextextViewiewcategory_txt.setPadding(10, 0, 0, 0);category_txt.setLayoutParams(params_wrapcontent);category_txt.setText(category); // 设置TextextViewiew显示的内容category_txt.setWidth(100);category_txt.setSingleLine();linearLayout.addView(category_txt);// 将textView添加到线性布局中// 规格TextView format_txt = new TextView(this);// 创建TextextViewiewformat_txt.setPadding(10, 0, 0, 0);format_txt.setLayoutParams(params_wrapcontent);format_txt.setText(format); // 设置TextextViewiew显示的内容format_txt.setWidth(50);linearLayout.addView(format_txt);// 将textView添加到线性布局中// 价格EditText price_editText = new EditText(this);price_editText.setId(id);price_editText.setPadding(10, 0, 0, 0);price_editText.setLayoutParams(params_wrapcontent);price_editText.setWidth(80);price_editText.setSingleLine();price_editText.setText(String.valueOf(id));// price_editText.setText("500ml"); // 设置TextextViewiew显示的内容linearLayout.addView(price_editText);// 将textView添加到线性布局中return linearLayout;}?
通过InFlate方式：
// 代码生成控件方法private LinearLayout newView(String category, String format, int id) {LayoutInflater inflater = LayoutInflater.from(ReportPrice.this);// 渲染器LinearLayout view = (LinearLayout)inflater.inflate(R.layout.reportprice_item, null);TextView variety_text = (TextView) view.findViewById(R.id.variety_text);variety_text.setText(category); // 设置TextextViewiew显示的内容TextView format_text = (TextView) view.findViewById(R.id.format_text);format_text.setText(format);EditText price_editText = (EditText) view.findViewById(R.id.price_et);price_editText.setText(String.valueOf(id));}?
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:orientation="horizontal" android:layout_width="fill_parent"android:layout_gravity="center" android:layout_height="wrap_content"><TextView android:layout_height="wrap_content"android:layout_width="fill_parent" android:id="@+id/variety_text"android:textSize="17sp" android:gravity="center"android:layout_gravity="center" android:layout_weight="1" /><TextView android:layout_height="fill_parent" android:id="@+id/format_text"android:layout_gravity="center" android:textSize="17sp"android:gravity="center" android:layout_weight="1"android:layout_width="fill_parent" /><EditText android:layout_height="wrap_content"android:inputType="numberDecimal" android:background="@drawable/username_bg"android:layout_width="fill_parent" android:id="@+id/price_et"android:layout_gravity="center" android:textSize="15dp"android:maxWidth="50dp"android:maxLength="10" android:gravity="center" android:layout_weight="1" /></LinearLayout>
