안드로이드 쓰레드가 작동하지 않습니다.

Question

내 애플리케이션의 배경 스레드에서 데이터를 실행하고 싶지만, 내 애플리케이션에서 해보았을 때 작동하지 않았습니다.

package com.example.mos.androidclientmymobile; 

import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.widget.TextView; 
import android.os.Handler;

다음은 (내가 지금까지 뭘하려합니다) 내 코드입니다.

Answer 1

는 다음과 같은 코드를 시도해보십시오. "작동하지 않습니다"

public class MainActivity extends AppCompatActivity { 

    private Handler handler; 

    ProgressDialog progressDialog; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     //without the Looper.getMainLooper should work too 
     handler = new Handler(Looper.getMainLooper()); 
     startProcessing(); 
    } 

    private void startProcessing() { 
     progressDialog = ProgressDialog.show(this, "Loading", "Loading data"); 
     t.start(); 
    } 


    Thread t = new Thread(new Runnable() { 
     @Override 
     public void run() { 
      try { 
       Thread.sleep(2000); 
       log("a new client connected"); 
      } catch (Exception e) { 
       Log.e("TAG", e.getLocalizedMessage()); 
      } 
     } 
    }); 

    public void log(final String message) { 
     handler.post(new Runnable() { 
      @Override 
      public void run() { 
       Toast.makeText(MainActivity.this, message, Toast.LENGTH_SHORT).show(); 
       progressDialog.dismiss(); 
      } 
     }); 
    } 
} 

xml can be as simple as: 
<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:paddingBottom="@dimen/activity_vertical_margin" 
    android:paddingLeft="@dimen/activity_horizontal_margin" 
    android:paddingRight="@dimen/activity_horizontal_margin" 
    android:paddingTop="@dimen/activity_vertical_margin"> 

    <TextView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="Hello World!" /> 
</RelativeLayout> 

//if the above code works for you then the problem is in some other place, but not the handler or UI thread.
