设置向导
> 演示搜狗输入法设置向导
> 完成第一个向导页面Setup1Activity的布局文件
- style样式介绍
- 用到的系统图片
android:drawableLeft="@android:drawable/star_big_on"//五角星
android:src="@android:drawable/presence_online" //小点选中
android:src="@android:drawable/presence_invisible" //小点不选中
selector介绍
1. 查看系统style.xml中有关Button样式的描述, 寻找Button的背景xml
<style name="Widget.Holo.Light.Button" parent="Widget.Button">
2. 查看谷歌官方文档, 了解selector的详细设置方法
App Resources>Resource Types>Drawable>State List
拷贝Example的代码,在项目中运行.使用美图秀秀作图 50*50
3. 使用准备好的图片创建新的selector, 设置给引导页面和Dialog
9patch图
> *.9.png
android手机上,可以按需求自动拉伸的图片
> 制作9Patch图: sdk/tools/draw9patch.bat
- 上边线控制水平拉伸
- 左边线控制竖直拉伸
- 右边线和下边线控制内容区域
完成4个设置引导页
1. Button 样式统一style
2. 上一页和下一页逻辑处理
完成手机防盗页布局
> "重新进入设置向导" 按钮样式调整, 使用TextView添加selector,
> android:clickable="true", 处理该按钮的点击事件
Shape介绍
1. 查看官方文档有关Shape的介绍
App Resources>Resource Types>Drawable>Shape Drawable
拷贝Example的代码,在项目中运行
2. 演示shape下的几个属性
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<!-- 圆角弧度 -->
<corners android:radius="5dp" />
<!-- 渐变 <gradient android:startColor="#ff0000" android:endColor="#00ff00" /> -->
<!-- 填充色 -->
<solid android:color="#fff" />
<!-- 边框(虚线) <stroke android:width="1dp" android:color="#000000" android:dashWidth="8dp" android:dashGap="3dp"/> -->
</shape>
Activity切换动画
> 下一页动画 trans_in.xml <?xml version="1.0" encoding="utf-8"?> <translate android:fromXDelta="100%p" android:toXDelta="0" android:duration="500" xmlns:android="http://schemas.android.com/apk/res/android"> </translate> trans_out.xml <?xml version="1.0" encoding="utf-8"?> <translate android:fromXDelta="0" android:toXDelta="-100%p" android:duration="500" xmlns:android="http://schemas.android.com/apk/res/android"> </translate> > 上一页动画 trans_pre_in.xml <?xml version="1.0" encoding="utf-8"?> <translate android:fromXDelta="-100%p" android:toXDelta="0" android:duration="500" xmlns:android="http://schemas.android.com/apk/res/android"> </translate> trans_pre_out.xml <?xml version="1.0" encoding="utf-8"?> <translate android:fromXDelta="0" android:toXDelta="100%p" android:duration="500" xmlns:android="http://schemas.android.com/apk/res/android"> </translate> > Activity切换的动画效果 > overridePendingTransition(R.anim.trans_in, R.anim.trans_out);//Activity切换的动画效果
手势识别器
detector = new GestureDetector(this,
new GestureDetector.SimpleOnGestureListener() {
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2,
float velocityX, float velocityY) {
if (Math.abs(e1.getRawY() - e2.getRawY()) > 100) {
Toast.makeText(BaseSetupActivity.this, "不能这样划哦!",
Toast.LENGTH_SHORT).show();
return true;
}
if (Math.abs(velocityX) < 100) {
Toast.makeText(BaseSetupActivity.this, "速度太慢啦!",
Toast.LENGTH_SHORT).show();
return true;
}
if (e2.getRawX() - e1.getRawX() > 200) {
Log.d("Test", "显示上一页");
showPrevious();
return true;
}
if (e1.getRawX() - e2.getRawX() > 200) {
Log.d("Test", "显示下一页");
showNext();
return true;
}
return super.onFling(e1, e2, velocityX, velocityY);
}
});
@Override
public boolean onTouchEvent(MotionEvent event) {
detector.onTouchEvent(event);
return super.onTouchEvent(event);
}
代码重构, 抽取父类
> BaseSetupActivity
// 展示下一页
public abstract void showNext();
// 展示上一页
public abstract void showPrevious();
// 下一页按钮点击
public void next(View view) {
showNext();
}
// 上一页按钮点击
public void previous(View view) {
showPrevious();
}
sim卡绑定页面实现(Setup2Activity)
TelephonyManager mTelePhonyManager; mTelePhonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE); String simSerialNumber = mTelePhonyManager.getSimSerialNumber();// 获取sim卡序列号 需要权限: <uses-permission android:name="android.permission.READ_PHONE_STATE"/> 将序列号保存在sp中,根据sp是否有值来更新选择框状态
监听开机启动,检测sim卡变化
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/> <receiver android:name=".receiver.BootCompleteReceiver" > <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED" /> </intent-filter> </receiver> 如果发现当前sim卡和sp中保存的不一致,需要向安全号码发送报警短信
读取联系人Demo
/**
* 读取联系人
*/
private ArrayList<HashMap<String, String>> readContacts() {
ArrayList<HashMap<String, String>> contacts = new ArrayList<HashMap<String, String>>();
ContentResolver resolver = getContentResolver();
Uri uriRaw = Uri.parse("content://com.android.contacts/raw_contacts");// raw_contacts表的uri
Uri uriData = Uri.parse("content://com.android.contacts/data");// data表的uri
Cursor cursor = resolver.query(uriRaw, new String[] { "contact_id" },
null, null, null);
if (cursor != null) {
while (cursor.moveToNext()) {
String id = cursor.getString(0);
Cursor dataCursor = resolver.query(uriData, new String[] {
"data1", "mimetype" }, "raw_contact_id=?",
new String[] { id }, null);
if (dataCursor != null) {
HashMap<String, String> map = new HashMap<String, String>();
while (dataCursor.moveToNext()) {
String data = dataCursor.getString(0);
String mimeType = dataCursor.getString(1);
if ("vnd.android.cursor.item/phone_v2".equals(mimeType)) {
map.put("phone", data);// 设置手机号码
} else if ("vnd.android.cursor.item/name"
.equals(mimeType)) {
map.put("name", data);// 设置名称
}
}
contacts.add(map);
}
}
}
return contacts;
}
SimpleAdapter adapter = new SimpleAdapter(this, contacts,
R.layout.list_contact_item, new String[] { "name", "phone" },
new int[] { R.id.tv_name, R.id.tv_phone });
lvList.setAdapter(adapter);
需要配置权限
<uses-permission android:name="android.permission.READ_CONTACTS" />
将联系人模块导入到项目中, 点击"选择联系人",跳转到联系人列表页
通过startActivityForResult方式跳转,可以获取联系人页面的回传数据
SelectContactActivity:
Intent intent = new Intent();
intent.putExtra("phone", phone);
setResult(Activity.RESULT_OK, intent);
finish();
-------------------
Setup3Activity:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
System.out.println("onActivityResult:" + resultCode);
if (resultCode == Activity.RESULT_OK) {
String phone = data.getStringExtra("phone");
phone = phone.replace("-", "");//去掉"-"
phone = phone.replace(" ", "");//去掉空格
etPhoneNumber.setText(phone);
}
super.onActivityResult(requestCode, resultCode, data);
}
<EditText
android:id="@+id/et_phone_number"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="phone"//设定键盘类型为电话号码
android:hint="请输入或选择安全号码"
>
//如果安全号码不为空,更新EditText
String phone = mSp.getString("safe_phone", null);
if (!TextUtils.isEmpty(phone)) {
etPhoneNumber.setText(phone);
}
//跳转下一个页面
String phone = etPhoneNumber.getText().toString().trim();// 过滤掉两侧空格后,获取号码信息
if (TextUtils.isEmpty(phone)) {
Toast.makeText(this, "必须设定安全号码!", Toast.LENGTH_SHORT).show();
return;
}
mSp.edit().putString("safe_phone", phone).commit();// 保存电话号码
防盗保护页面状态更新(LostFindActivity)
//判断防盗保护是否开启,更新图标状态
boolean protecting = sp.getBoolean("protecting", false);
if (protecting) {
ivProtect.setImageResource(R.drawable.lock);
} else {
ivProtect.setImageResource(R.drawable.unlock);
}
tvSafePhone.setText(sp.getString("safe_phone", ""));
//更新安全号码
