线程池FixedThreadPool

可重用线程池,只有核心线程,并发无阻塞,

public class MainActivity extends AppCompatActivity {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        final ExecutorService fixedThreadPool = Executors.newFixedThreadPool(5);
        for(int i = 0;i<30;i++){
            final int finali = i;
            Runnable runnable = new Runnable() {
                @Override
                public void run() {
                    try {
                        Thread.sleep(2000);
                        Log.d("Thread", "run: "+finali);
                        Log.d("当前线程：",Thread.currentThread().getName());
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
            };
            fixedThreadPool.execute(runnable);

        }
    }
}
