迁移源地址为：《Android开发动画向左向右动画，TextView设置下划线，String[]数组转换，缓存历史纪录备份》
首先，这边文章给自己的一个备份，最近工作太久发现记忆力有所下降，所以做一个笔记，省得到处博客翻阅，
1，向左向右动画，
llAccount.setAnimation(AnimationUtils.makeOutAnimation(this, false));//向左移出
llVerify.setAnimation(AnimationUtils.makeInAnimation(this, false));//向左移入
//animation llAccount.setAnimation(AnimationUtils.makeInAnimation(this, true));//向右移入
llVerify.setAnimation(AnimationUtils.makeOutAnimation(this, true));//向右移出
2，TextView设置下划线可点击，网页
mUserRoot.setText(Html.fromHtml(“<a href="http://www.miracase.com/brand.asp">iBreezee用户协议</a>”));
tvNewAccount = (TextView) findViewById(R.id.tvNewAccount);
tvNewAccount.getPaint().setFlags(Paint.UNDERLINE_TEXT_FLAG);
3，String[]数值转化为ListView
if (resultCode == RESULT_OK) {
bundle = data.getExtras();
String listsString = bundle.getString(“listsString”);
if (!TextUtils.isEmpty(listsString)) {
try {
if (listsString.contains(“[”)) {
String subString = listsString.substring(1, listsString.length() - 1);
String[] listArray = subString.replace(“ “, “”).split(“,”);
// List lists = Arrays.asList(listArray);//也可以，这里有space的坑。
// System.out.println(getClass().getName() + "---qydq--测试lists--" + lists.toString());
StringBuffer codesBuffer = new StringBuffer();
for (String list : listArray) {
String code = list.substring(list.length() - 12, list.length());
codesBuffer.append(code + "@");
}
code = codesBuffer.toString().substring(0, codesBuffer.length() - 1);
} else {
Toast.makeText(x.app(), "没有[" + listsString, Toast.LENGTH_LONG).show();
}
System.out.println(getClass().getName() + "---qydq--测试code--" + code);
} catch (Exception e) {
e.printStackTrace();
}
}
4，缓存历史数据，like用户名，密码，啥的。
1）存
mHistoryKeywords = new ArrayList();
String oldText = preferences.getString("username", "");
String oldPass = preferences.getString("password", "");
StringBuilder builder = new StringBuilder(username);
StringBuilder bdps = new StringBuilder(password);
builder.append("," + oldText);
bdps.append("," + oldPass);
if (!TextUtils.isEmpty(username) && !oldText.contains(username + ",")) {
SharedPreferences.Editor editor = preferences.edit();
editor.putString("username", builder.toString());//username作为list会使用到
editor.putString("password", bdps.toString());//username作为list会使用到
editor.putString("account", username);
editor.putString("pwd", password);
mHistoryKeywords.add(0, username);
editor.commit();
}
2）取
// 一个自定义的布局，作为显示记录的内容
public void showPopupWindow(View view) {
View contentView = LayoutInflater.from(mContext).inflate(R.layout.sst_activity_login_popwind, null);
ListView listView = (ListView) contentView.findViewById(R.id.lvLogin);
String history = preferences.getString(“username”, “”);
String password = preferences.getString(“password”, “”);
final String[] mHistoryArr = history.split(“,”);
final String[] passwordArr = password.split(“,”);
ArrayAdapter mArrAdapter = new ArrayAdapter(mContext, android.R.layout.simple_list_item_1, mHistoryArr);
listView.setAdapter(mArrAdapter);
mArrAdapter.notifyDataSetChanged();
final PopupWindow popupWindow = new PopupWindow(contentView, ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT, true);
popupWindow.setTouchable(true);
popupWindow.setTouchInterceptor(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
Log.i(TAG, "onTouch : ");
return false;
// 这里如果返回true的话，touch事件将被拦截
// 拦截后 PopupWindow的onTouchEvent不被调用，这样点击外部区域无法dismiss
}
});
// 如果不设置PopupWindow的背景，无论是点击外部区域还是Back键都无法dismiss弹框
// 我觉得这里是API的一个bug
popupWindow.setBackgroundDrawable(getResources().getDrawable(R.drawable.wt_drawable_arrow_history));
// 设置好参数之后再show
popupWindow.showAsDropDown(view);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
popupWindow.dismiss();
if (mHistoryArr.length != 0) {
editText1.setText(mHistoryArr[position]);
editText2.setText(passwordArr[position]);
}
}
});
}
