Question

 自己想看网上练习做一个 起始页 倒计时5秒之后 跳转到后面一页 可以跳过 

但是我按跳过之后 倒计时不知道为什么还没有结束 之后就跳转了第2遍。

import java.util.Timer;
import java.util.TimerTask;

import com.sicp.animeappczl.R;

import android.os.Bundle;
import android.os.Handler;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Window;
import android.view.WindowManager;
import android.widget.TextView;

public class StartActivity extends Activity implements View.OnClickListener {
	
	
	 private int recLen = 5;//跳过倒计时提示5秒
	    private TextView tv;
	    Timer timer = new Timer();
	    private Handler handler;
	    private Runnable runnable;


	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		//隐藏标题栏
		 int flag= WindowManager.LayoutParams.FLAG_FULLSCREEN;
	     requestWindowFeature(Window.FEATURE_NO_TITLE);
		    //设置当前窗体为全屏显示
	        getWindow().setFlags(flag, flag);
	        setContentView(R.layout.activity_start);
	        initView();
	        timer.schedule(task, 1000, 1000);//等待时间一秒，停顿时间一秒
	        /**
	         * 正常情况下不点击跳过
	         */

		
		new Handler().postDelayed(new Runnable() {
			
			@Override
			public void run() {
				// TODO Auto-generated method stub
				Intent intent=new Intent(StartActivity.this,MainActivity.class);
				startActivity(intent);
				finish();
			}
		},5500);
		
	}

	  private void initView() {
	        tv = (TextView) findViewById(R.id.tv);//跳过
	        tv.setOnClickListener((OnClickListener) this);//跳过监听
	    }
	 
	    TimerTask task = new TimerTask() {
	        @Override
	        public void run() {
	            runOnUiThread(new Runnable() { // UI thread
	                @Override
	                public void run() {
	                    recLen--;
	                    tv.setText("跳过 " + recLen);
	                    if (recLen < 0) {
	                        timer.cancel();
	                        tv.setVisibility(View.GONE);//倒计时到0隐藏字体
	                    }
	                }
	            });
	        }
	    };
	 
	    /**
	     * 点击跳过
	     */
	    @Override
	    public void onClick(View view) {
	        switch (view.getId()) {
	            case R.id.tv:
	                //从闪屏界面跳转到首界面
	                Intent intent = new Intent(StartActivity.this, MainActivity.class);
	                startActivity(intent);
	                finish();
	                if (runnable != null) {
	                    handler.removeCallbacks(runnable);
	                    
	                }
	                break;
	            default:
	                break;
	        }


	    }
}

楼上的只回答对了一半。handle和runnable都没定义，修改以下两处代码即可，亲测有效。

//handle重新定义    
private static final Handler handler = new Handler(Looper.getMainLooper());

//再定义下runnable
    /**
         * 正常情况下不点击跳过
         */
        handler.postDelayed(runnable,5500);

        runnable=new Runnable() {
            @Override
            public void run() {
                // TODO Auto-generated method stub
                Intent intent=new Intent(TestActivity.this,MainActivity.class);
                startActivity(intent);
                finish();
            }
        };
