使用webview加載html5
由於涉及定位功能
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION)
!= PackageManager.PERMISSION_GRANTED
|| ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED
|| ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED) {
Toast.makeText(getApplicationContext(),"沒有權限,請手動開啟定位權限",Toast.LENGTH_SHORT).show();
ActivityCompat.requestPermissions(MainActivity.this,new String[]{Manifest.permission.ACCESS_COARSE_LOCATION, Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.WRITE_EXTERNAL_STORAGE}, 100);
return false;
}
開啟權限之后，webView開啟地理位置功能
WebView webView = (WebView)findViewById(R.id.webview);
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setDatabaseEnabled(true);
String dir = this.getApplicationContext().getDir("database", Context.MODE_PRIVATE).getPath();
webSettings.setGeolocationDatabasePath(dir);
webSettings.setGeolocationEnabled(true); //啟用地理定位
webSettings.setDomStorageEnabled（true）
webView.setWebChromeClient(new WebChromeClient() {
@Override
public void onReceivedIcon(WebView view, Bitmap icon) {
super.onReceivedIcon(view, icon);
}
@Override
public void onGeolocationPermissionsShowPrompt(String origin,Callback callback) {
callback.invoke(origin, true, false);
super.onGeolocationPermissionsShowPrompt(origin, callback);
}
});
