我有一项活动。我想要的是如果用户在一段时间后(由x表示)处于非活动状态,则此活动将自动完成。感谢所有帮助。

我的示例代码:

package com.zilant.testapp;

import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;


public class HelpActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_help);
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_help, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

这是一段活动代码,会在五秒后自动关闭。

public class TestActivity extends ActionBarActivity {


private static final int DELAY = 5000;

public boolean inactive;

Handler mHideHandler = new Handler();
Runnable mHideRunnable = new Runnable() {        
    @Override
    public void run() {            
        if(inactive) {
            finish();
        } else {
            mHideHandler.postDelayed(mHideRunnable, DELAY);
        }
    }
};

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_annotation_test);
    mHideHandler.postDelayed(mHideRunnable, DELAY);

}
}

现在您需要做的就是在用户交互后将非活动变量更改为true。这将取消活动结束并开始新的倒计时。
