Java代码：
我正在使用firebase将json存储为数据库，然后我将其作为String检索并转换为Jsonobject
public class StartActivity extends AppCompatActivity{
Toolbar ToolbarStart;
private DrawerLayout mDrawerLayout;
ActionBarDrawerToggle mDrawerToggle;
NavigationView mNavigationView;
FirebaseDatabase database = FirebaseDatabase.getInstance();
DatabaseReference mDatabase = database.getReference();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_start);
initilize();
initilizeNavigationDrawer();
getSupportFragmentManager().beginTransaction().replace(R.id.startContainer,new GymChartFragment()).commit();
mDatabase.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
try {
JSONObject obj = new JSONObject(dataSnapshot.getValue()+"");
JSONArray arr = obj.getJSONArray("day");
Log.d("Size",arr.length()+"");
} catch (JSONException e) {
e.printStackTrace();
}
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
});
}
private void initilizeNavigationDrawer() {
mDrawerLayout = (DrawerLayout)findViewById(R.id.startDrawerLayout);
mNavigationView = (NavigationView)findViewById(R.id.mainNaviagtionView);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, ToolbarStart, R.string.drawerOpen, R.string.drawerClose) {
@Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
}
@Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
mDrawerToggle.syncState();
mNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
@Override

switch (item.getItemId()){

你的json是有效的，我设法通过解析为JsonObject来解析它。
String jsonString = loadJSONFromAsset();
try {
JSONObject jsonObject = new JSONObject(jsonString);
Log.d("2#","@");
} catch (JSONException e) {
e.printStackTrace();
}
}
public String loadJSONFromAsset() {
String json = null;
try {
InputStream is = getAssets().open("index.json");
int size = is.available();
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
json = new String(buffer, "UTF-8");
} catch (Exception ex) {
ex.printStackTrace();
return null;
}
return json;
}
