Android項(xiàng)目總結(jié)3
最近又獨(dú)立開發(fā)了一個(gè)公司內(nèi)部的小app，現(xiàn)在的感覺就是每一次獨(dú)立開發(fā)一個(gè)新的app，都會(huì)遇到不同的問題，也都能獨(dú)立解決這些問題。感覺這個(gè)狀態(tài)還可以吧，同時(shí)打算把這些問題記錄一下，以后再遇到同樣問題的時(shí)候，有一個(gè)可以查閱的資料，也能幫助其它遇到同樣問題的小伙伴們吧。
本次項(xiàng)目采用的網(wǎng)絡(luò)框架：rxjava + retrofit2,這個(gè)就不在這里總結(jié)了，有空會(huì)單獨(dú)總結(jié)一篇有關(guān)文章的。
獲取屏幕寬度
public int getScreenWidth(){
WindowManager wm = (WindowManager) this.getSystemService(Context.WINDOW_SERVICE);
DisplayMetrics dm = new DisplayMetrics();
wm.getDefaultDisplay().getMetrics(dm);
int width = dm.widthPixels; // 屏幕寬度（像素）
int height = dm.heightPixels; // 屏幕高度（像素）
float density = dm.density; // 屏幕密度（0.75 / 1.0 / 1.5）
int densityDpi = dm.densityDpi; // 屏幕密度dpi（120 / 160 / 240）
// 屏幕寬度算法:屏幕寬度（像素）/屏幕密度
int screenWidth = (int) (width / density); // 屏幕寬度(dp)
int screenHeight = (int) (height / density);// 屏幕高度(dp)
return width;

- 獲取屏幕高度

getAndroiodScreenProperty();
return height;

- 自定義異常

- 自定義OnClickListener防止重復(fù)點(diǎn)擊發(fā)生的問題

if (time - lastClickTime > MIN_CLICK_DELAY_TIME) {
lastClickTime = time;
onNoDoubleClick(v);
}
}
public abstract void onNoDoubleClick(View v);
}
- 創(chuàng)建notification并且添加點(diǎn)擊事件
PendingIntent mainPendingIntent = null;
Intent mainIntent = new Intent(this, MainActivity.class);
mainPendingIntent = PendingIntent.getActivity(this, 0, mainIntent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationManager mNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this);
mBuilder.setContentTitle("您有新的訂單,請(qǐng)登陸app查看")//設(shè)置通知欄標(biāo)題
.setContentIntent(getDefalutIntent(Notification.FLAG_AUTO_CANCEL)) //設(shè)置通知欄點(diǎn)擊意圖
// .setNumber(number) //設(shè)置通知集合的數(shù)量
.setTicker("您有新的訂單,請(qǐng)登陸app查看") //通知首次出現(xiàn)在通知欄，帶上升動(dòng)畫效果的
.setWhen(System.currentTimeMillis())//通知產(chǎn)生的時(shí)間，會(huì)在通知信息里顯示，一般是系統(tǒng)獲取到的時(shí)間
.setContentIntent(mainPendingIntent)
.setPriority(Notification.PRIORITY_DEFAULT) //設(shè)置該通知優(yōu)先級(jí)
.setAutoCancel(true)//設(shè)置這個(gè)標(biāo)志當(dāng)用戶單擊面板就可以讓通知將自動(dòng)取消
.setOngoing(false)//ture，設(shè)置他為一個(gè)正在進(jìn)行的通知。他們通常是用來表示一個(gè)后臺(tái)任務(wù),用戶積極參與(如播放音樂)或以某種方式正在等待,因此占用設(shè)備(如一個(gè)文件下載,同步操作,主動(dòng)網(wǎng)絡(luò)連接)
.setDefaults(Notification.DEFAULT_VIBRATE)//向通知添加聲音、閃燈和振動(dòng)效果的最簡(jiǎn)單、最一致的方式是使用當(dāng)前的用戶默認(rèn)設(shè)置，使用defaults屬性，可以組合
//Notification.DEFAULT_ALL Notification.DEFAULT_SOUND 添加聲音 // requires VIBRATE permission
.setSmallIcon(R.mipmap.ic_launcher);//設(shè)置通知小ICON
mNotificationManager.notify(1, mBuilder.build());
- 獲取Imei，兼容Android N(easypermission)
public class LoginActivity extends AppCompatActivity implements EasyPermissions.PermissionCallbacks {

} else {
Log.e("lin", "---lin---> imie else");
EasyPermissions.requestPermissions(this, "正在申請(qǐng)獲取手機(jī)唯一編碼",
100, perms);
}
}
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
// Forward results to EasyPermissions
EasyPermissions.onRequestPermissionsResult(requestCode, permissions, grantResults, this);

- 倒計(jì)時(shí)控件

@Override
public void onFinish() {// 計(jì)時(shí)完畢
tvGetCodeActivityLogin.setText("獲取驗(yàn)證碼");
tvGetCodeActivityLogin.setClickable(true);
}
@Override
public void onTick(long millisUntilFinished) {// 計(jì)時(shí)過程
long time = millisUntilFinished / 1000;
String timeString = String.valueOf(time);
timeString = timeString + "S";
tvGetCodeActivityLogin.setText(timeString);
tvGetCodeActivityLogin.setClickable(false);//防止重復(fù)點(diǎn)擊
}
}
- 設(shè)置editext hint字的顏色值
CharSequence hint = edtAuthCodeActivityLogin.getHint();
SpannableString ss = new SpannableString(hint);
AbsoluteSizeSpan ass = new AbsoluteSizeSpan(17, true);
edtAuthCodeActivityLogin.setHintTextColor(0xffdddddd);
ss.setSpan(ass, 0, ss.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
edtAuthCodeActivityLogin.setHint(new SpannedString("短信驗(yàn)證碼"));
App內(nèi)采用的開源相冊(cè) Album

fragment類似activity的onResume()
protected boolean isCreate = false;
@Override
public void setUserVisibleHint(boolean isVisibleToUser) {
super.setUserVisibleHint(isVisibleToUser);
if (isVisibleToUser && isCreate) {
getOrderList("-1");
}
}
- 利用反射設(shè)置tablayout下劃線長(zhǎng)度
tabLayoutOrderFragment.post(new Runnable() {
@Override
public void run() {
setIndicator(tabLayoutOrderFragment,20,20);
}
});
public void setIndicator(TabLayout tabs, int leftDip, int rightDip) {
