App在與服務(wù)器進(jìn)行網(wǎng)絡(luò)交互的時(shí)候，需要有一個(gè)提示的加載框，如圖：
創(chuàng)新互聯(lián)服務(wù)項(xiàng)目包括濮陽網(wǎng)站建設(shè)、濮陽網(wǎng)站制作、濮陽網(wǎng)頁制作以及濮陽網(wǎng)絡(luò)營銷策劃等。多年來，我們專注于互聯(lián)網(wǎng)行業(yè)，利用自身積累的技術(shù)優(yōu)勢(shì)、行業(yè)經(jīng)驗(yàn)、深度合作伙伴關(guān)系等，向廣大中小型企業(yè)、政府機(jī)構(gòu)等提供互聯(lián)網(wǎng)行業(yè)的解決方案，濮陽網(wǎng)站推廣取得了明顯的社會(huì)效益與經(jīng)濟(jì)效益。目前，我們服務(wù)的客戶以成都為中心已經(jīng)輻射到濮陽省份的部分城市，未來相信會(huì)繼續(xù)擴(kuò)大服務(wù)區(qū)域并繼續(xù)獲得客戶的支持與信任！
此時(shí)我們可以自定義一個(gè)加載中的對(duì)話框，代碼如下：

重慶分公司
public class LoadingDialog extends Dialog {
private static final int CHANGE_TITLE_WHAT = 1;
private static final int CHNAGE_TITLE_DELAYMILLIS = 300;
private static final int MAX_SUFFIX_NUMBER = 3;
private static final char SUFFIX = '.';
private ImageView iv_route;
private TextView detail_tv;
private TextView tv_point;
private RotateAnimation mAnim;
private Handler handler = new Handler() {
private int num = 0;
public void handleMessage(android.os.Message msg) {
if (msg.what == CHANGE_TITLE_WHAT) {
StringBuilder builder = new StringBuilder();
if (num >= MAX_SUFFIX_NUMBER) {
num = 0;
}
num++;
for (int i = 0; i < num; i++) {
builder.append(SUFFIX);
}
tv_point.setText(builder.toString());
if (isShowing()) {
handler.sendEmptyMessageDelayed(CHANGE_TITLE_WHAT, CHNAGE_TITLE_DELAYMILLIS);
}
else {
num = 0;
}
}
};
};
public LoadingDialog(Context context) {
super(context, R.style.Dialog_bocop);
init();
}
public LoadingDialog(Context context, boolean isTrans) {
super(context, isTrans ? R.style.Loading_Dialog_trans : R.style.Dialog_bocop);
init();
}
private void init() {
setContentView(R.layout.common_dialog_loading_layout);
iv_route = (ImageView) findViewById(R.id.iv_route);
detail_tv = (TextView) findViewById(R.id.detail_tv);
tv_point = (TextView) findViewById(R.id.tv_point);
initAnim();
getWindow().setWindowAnimations(R.anim.alpha_in);
}
private void initAnim() {
// mAnim = new RotateAnimation(360, 0, Animation.RESTART, 0.5f, Animation.RESTART, 0.5f);
mAnim = new RotateAnimation(0, 360, Animation.RESTART, 0.5f, Animation.RESTART, 0.5f);
mAnim.setDuration(2000);
mAnim.setRepeatCount(Animation.INFINITE);
mAnim.setRepeatMode(Animation.RESTART);
mAnim.setStartTime(Animation.START_ON_FIRST_FRAME);
}
@Override
public void show() {//在要用到的地方調(diào)用這個(gè)方法
iv_route.startAnimation(mAnim);
handler.sendEmptyMessage(CHANGE_TITLE_WHAT);
super.show();
}
@Override
public void dismiss() {
mAnim.cancel();
super.dismiss();
}
@Override
public void setTitle(CharSequence title) {
if (TextUtils.isEmpty(title)) {
detail_tv.setText("正在加載");
}
else {
detail_tv.setText(title);
}
}
@Override
public void setTitle(int titleId) {
setTitle(getContext().getString(titleId));
}
public static void dismissDialog(LoadingDialog loadingDialog) {
if (null == loadingDialog) { return; }
loadingDialog.dismiss();
}
}
-------------對(duì)應(yīng)的布局如下------------------
<?xml version="1.0" encoding="utf-8"?>
比如在Activity中要實(shí)現(xiàn)加載對(duì)話框調(diào)用 ：
LoadingDialog loadingDialog ;
if (null == loadingDialog) {
loadingDialog = new LoadingDialog(aty);
loadingDialog.setOnCancelListener(this);
}
loadingDialog.setTitle(“數(shù)據(jù)加載中”);
if (!loadingDialog.isShowing()) loadingDialog.show(); 以上就是本文的全部內(nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持創(chuàng)新互聯(lián)。
