必須先開啟“允許模擬地點”
方法： 打開設備的，設置 - 應用程序 - 開發 - “允許模擬地點”
1.在 AndroidManifest.xml 里添加相應的 “允許模擬位置的權限”
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION"/>
2.創建 一個 “用於模擬的坐標提供者”
LocationManager locationManager = (LocationManager) mContext
.getSystemService(Context.LOCATION_SERVICE);
if (locationManager.getProvider(mMockProviderName) == null) {
locationManager.addTestProvider(mMockProviderName, false, true,
false, false, false, false, false, 0, 5);
locationManager.setTestProviderEnabled(mMockProviderName, true);
}
注意：mMockProviderName 是你隨意定的名稱，后面在使用（獲得位置）時，用這個名稱。
3.構建（模擬的）坐標位置
Location loc = new Location(mMockProviderName);
loc.setTime(System.currentTimeMillis());
loc.setLatitude(latitude);
loc.setLongitude(longitude);
locationManager.setTestProviderLocation(mMockProviderName, loc);
Log.i("gps", String.format("once: x=%s y=%s", longitude, latitude));
注意：我們可以多次間歇的調用此方法來 模擬 位置的變化。
4.獲得（使用）坐標位置。
loc = (LocationManager) context
.getSystemService(Context.LOCATION_SERVICE);
loc.requestLocationUpdates(NAME_MOCK_GPS_PROVIDER, 1000, 10,
mListener);
這里的NAME_MOCK_GPS_PROVIDER的名稱 和前面“第2步”里名稱是一致的。
好了。讓代碼跑起來。
