解决Only the original thread that created a view hierarchy can touch its views

Only the original thread that created a view hierarchy can touch its views

translates to: Only the original thread that created a view hierarchy can touch its views

Reason:回调接口在子线程，并在回调接口对UI进行了操作

So, the above prompt will appear

Generally speaking, handle will be used to solve this problem

Different messages are passed on the corresponding callback interface according to the data returned by the network request

handler.sendMessage(msg);

Perform further operations based on the content of the message

private Handler handler = new Handler()
{
    
    
    @Override
    public void handleMessage(Message msg) {
    
    
        super.handleMessage(msg);
        switch (msg.what)
        {
    
    
            case 1:
                ...
                break;
        }
    }
};

There is another solution that saves trouble

Use runOnUiThread() directly

But if you use it too much, the code will not be refreshing.

MainActivity.this.runOnUiThread(new Runnable() {
    
    
    public void run() {
    
    
        ...
    }
});

If it is a fragment:

getActivity.runOnUiThread(new Runnable() {
    
    
            public void run() {
    
    
                ...
            }
        });
