本文介绍了一种基于Android的应用程序中实现页面跳转的方法，并通过手势识别来触发这些跳转。具体包括自定义基类Activity以处理通用的跳转逻辑，以及在子类活动中实现具体的跳转行为。

另外两个抽象方法是在页面上添加的按钮实现按钮点击之后页面的跳转；具体代码如下；

package com.xu.shoujiweishi.activity;

import android.app.Activity;
import android.os.Bundle;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;

public  abstract  class BaseActivity extends Activity {
    private GestureDetector mGestureDetector ;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        mGestureDetector=new GestureDetector(this, new GestureDetector.SimpleOnGestureListener(){
            @Override
            public boolean onFling(MotionEvent e1, MotionEvent e2,
                    float velocityX, float velocityY) {
                if (e1.getRawX()-e2.getRawX()>100) {
                    nextPage();
                }else if (e2.getRawX()-e1.getRawX()>100) {
                    prePage();

                }
                return super.onFling(e1, e2, velocityX, velocityY);
            }
        });


    }
    @Override
    public boolean onTouchEvent(MotionEvent event) {
        mGestureDetector.onTouchEvent(event);
        return super.onTouchEvent(event);
    }
    public  void nextpage(View view){
        nextPage();

    };
    public  void prepage(View view){

         prePage();
    };
    public abstract void nextPage();
    public abstract void prePage();

}

以下是子类的具体实现；

package com.xu.shoujiweishi.activity;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;

import com.xu.shouji.R;

public class SetUp1Activity extends BaseActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_set_up1);
    }

    @Override
    public void nextPage() {
        // TODO Auto-generated method stub
        Intent intent = new Intent(this, SetUp2Activity.class);
        startActivity(intent);
        finish();
        overridePendingTransition(R.anim.next_in, R.anim.next_out);
        // TODO Auto-generated method stub

    }

    @Override
    public void prePage() {//第一个界面没有上一页面；所以就不进行具体实现了；


    }

}

第二个界面

package com.xu.shoujiweishi.activity;

import android.app.Activity;
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.support.annotation.BoolRes;
import android.telephony.TelephonyManager;
import android.text.TextUtils;
import android.view.View;
import android.view.View.OnClickListener;

import com.xu.shouji.R;
import com.xu.shoujiweishi.util.ConstantValue;
import com.xu.shoujiweishi.util.SpUtil;
import com.xu.shoujiweishi.util.ToastUtil;
import com.xu.shoujiweishi.view.SettingItemView;

public class SetUp2Activity extends BaseActivity {
    private SettingItemView siv;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_set_up2);
        initUI();

    }

    private void initUI() {
        // TODO Auto-generated method stub
        siv = (SettingItemView) findViewById(R.id.siv_sim_bound);
        // 回显；
        String sim_no = SpUtil.getString(this, ConstantValue.SIM_NO, "");
        if (TextUtils.isEmpty(sim_no)) {
            siv.setChecked(false);
        } else {
            siv.setChecked(true);
        }
        siv.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                boolean ischeck = siv.isCheck();

                siv.setChecked(!ischeck);
                if (!ischeck) {
                    // 存储序列卡号
                    TelephonyManager manager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
                    String serialNumber = manager.getSimSerialNumber();
                    SpUtil.putString(getApplicationContext(),
                            ConstantValue.SIM_NO, serialNumber);

                } else {
                    // 删除序列卡号的节点；
                    SpUtil.remove(getApplicationContext(), ConstantValue.SIM_NO);
                }

            }
        });

    }





    @Override
    public void nextPage() {
        // TODO Auto-generated method stub
        String string = SpUtil.getString(this, ConstantValue.SIM_NO, "");
        if (!TextUtils.isEmpty(string)) {
            Intent intent = new Intent(this, SetUp3Activity.class);
            startActivity(intent);
            finish();
            overridePendingTransition(R.anim.next_in, R.anim.next_out);
        }else {
            ToastUtil.show(this, "请绑定手机卡号");
        }
    }

    @Override
    public void prePage() {
        // TODO Auto-generated method stub
        Intent intent = new Intent(this, SetUp1Activity.class);
        startActivity(intent);
        finish();
        overridePendingTransition(R.anim.pre_in, R.anim.pre_out);
    }

}
