如果写插入location:
final class LocationHelper { private LocationListener mLocationListener; private WriteBlog activity; private LocationManager mLocationManager; // 默认延迟。单位:秒 private int timeout; private Handler uiHandler; private boolean isLocated; private LocationHolder holder; private boolean startFetching; private String defaultDraftPath; LocationHelper(WriteBlog activity) { this.activity = activity; mLocationManager = (LocationManager) activity .getSystemService(Context.LOCATION_SERVICE); uiHandler = new Handler(); timeout = 60; defaultDraftPath = activity.getFilesDir().getAbsolutePath() + "/draft/location.dat"; } void dispose() { closeAll(); isLocated = false; startFetching = false; holder = null; } void openAllProviders() { if (startFetching || isLocated) { return; } requestProviders(); } boolean isFetching() { return startFetching; } boolean isLocatedSucess() { return (holder != null) && holder.isUseful(); } void closeAll() { if (mLocationListener != null) { mLocationManager.removeUpdates(getLocationListener()); mLocationListener = null; } } private LocationListener getLocationListener() { if (mLocationListener == null) { mLocationListener = new LocationListener() { public void onLocationChanged(Location location) { final LocationHolder holder = new LocationHolder(); holder.lat = location.getLatitude(); holder.lon = location.getLongitude(); System.out.println("====holder.lat="+holder.lat+"lon="+holder.lon); if (holder.isUseful()) { isLocated = true; LocationHelper.this.holder = holder; activity.onLocatedSuccess(); closeAll(); startFetching = false; } } public void onProviderDisabled(String provider) { } public void onProviderEnabled(String provider) { } public void onStatusChanged(String provider, int status, Bundle extras) { } }; } return mLocationListener; } private void requestProviders() { final List<String> providers = mLocationManager.getProviders(true); boolean requestSuccess = false; if (providers.contains(LocationManager.GPS_PROVIDER)) { mLocationManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, 0, 0, getLocationListener()); requestSuccess = true; } if (providers.contains(LocationManager.NETWORK_PROVIDER)) { mLocationManager.requestLocationUpdates( LocationManager.NETWORK_PROVIDER, 0, 0, getLocationListener()); requestSuccess = true; } if (requestSuccess) { activity.pgLoadingLocation.setVisibility(View.VISIBLE); startFetching = true; if (timeout > 0) { uiHandler.postDelayed(new Runnable() { public void run() { if (!isLocated && (activity != null) && !activity.isFinishing()) { closeAll(); activity.onLocatedError(); startFetching = false; } } }, timeout * 1000); } } } } final class LocationHolder implements Serializable { private static final long serialVersionUID = -8205421689204807445L; double lat; double lon; public boolean equals(Object o) { if (o == null) { return false; } if (o == this) { return true; } if (o.getClass() == getClass()) { final LocationHolder holder = (LocationHolder) o; if ((Math.abs(holder.lat - lat) < .001) && (Math.abs(holder.lon - lon) < .001)) { return true; } } return false; } public int hashCode() { final StringBuffer builder = new StringBuffer(); builder.append(lat).append(lon); return builder.hashCode(); } boolean isUseful() { return islegal(lat) && islegal(lon); } private boolean islegal(double pos) { if ((pos > 1.) || (pos < -1.)) { return true; } return false; } }

然后这里来关注点击事件
final class FaceClickHealper { private boolean isFaceDiaplay = false; private WriteBlog activity; boolean isFaceDiaplay() { return isFaceDiaplay; } <strong>void onClick(View v) { activity.setEmotionViewVisibility(!isFaceDiaplay); if (isFaceDiaplay) { activity.displayFaceImageSrc(); } else { activity.displayKeyboardImageSrc(); } activity.setInputMethodVisibility(isFaceDiaplay); changeDiaplayFlag(); }//这个是点击事件</strong> boolean onFinish() { if (isFaceDiaplay) { activity.displayFaceImageSrc(); activity.setEmotionViewVisibility(false); changeDiaplayFlag(); return true; } return false; } private void changeDiaplayFlag() { isFaceDiaplay = !isFaceDiaplay; } public FaceClickHealper(WriteBlog activity) { super(); this.activity = activity; } }
void displayFaceImageSrc() { if (ibFace != null) { ibFace.setImageResource(R.drawable.btn_insert_face); } } void displayKeyboardImageSrc() { if (ibFace != null) { ibFace.setImageResource(R.drawable.btn_insert_keyboard); } } boolean setInputMethodVisibility(boolean visibility) { if ((mInputMethodManager != null) && (etMblog != null)) { if (visibility) { mInputMethodManager.showSoftInput(etMblog, 0); } else { if (mInputMethodManager.isActive(etMblog)) { mInputMethodManager.hideSoftInputFromWindow( etMblog.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS); } } } return false; } <pre name="code" class="java"><span style="white-space:pre"> </span>void setEmotionViewVisibility(boolean visibility) { if (mEmotionView != null) { mEmotionView.setVisibility(visibility ? View.VISIBLE : View.GONE); } }
