手机防盗模块

首先是实现滑屏操作的类：

<p>package com.cbd.safemobile;</p><p>import com.example.safemobile_test.R;</p><p>import android.app.Activity;
import android.content.Context;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.util.Log;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;</p><p>public abstract class BaseSetupWizardActivity extends Activity {
     //定义共享存储偏号
  protected SharedPreferences ps;
  //定义手势识别器
  protected GestureDetector mGestureDetector;
  protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   ps=getSharedPreferences("config", Context.MODE_PRIVATE);
   mGestureDetector=new GestureDetector(new GestureDetector.SimpleOnGestureListener(){
    //手指在屏幕上做手势时，调用该方法
    public boolean onFling(MotionEvent e1, MotionEvent e2,
      float velocityX, float velocityY) {
     
      if(Math.abs(e1.getRawY() - e2.getRawY())>200)
      {
      Log.i("BaseSetupWizardActivity","垂直方向移动过大,动作不合法");
      return true;
      }
     
      if(Math.abs(velocityX)<50)
      {
      Log.i("BaseSetupWizardActivity","滑动的太慢,动作不合法");
      return true;
      }
      if(e2.getRawX()-e1.getRawX()>200)
      {  
       //showPre();
       pre(null);
       return true;
      }
      if(e1.getRawX()-e2.getRawX()>200)
                                 {  
       //showNext();
       next(null);
       return true;
      }  
      return super.onFling(e1, e2, velocityX, velocityY);
    }
    
   });
   setupView();
   findView();
   
   
  }
  
  //当手指在屏幕上触摸的时候调用的方法.
    @Override
    public boolean onTouchEvent(MotionEvent event) {
     //3.让手势识别器生效
     mGestureDetector.onTouchEvent(event);
     return super.onTouchEvent(event);
    }
    
    
   public abstract void setupView();
   
   public abstract void findView();
   
   public abstract void showNext();
   public abstract void showPre();
   
   public void next(View v)
   {
    showNext();
    overridePendingTransition(R.anim.tran_in_next, R.anim.tran_out_next);
   }
   public void pre(View v)
   {
    showPre();
    overridePendingTransition(R.anim.tran_in</p><p>
_pre, R.anim.tran_out_pre);
   }
}

</p><p> </p>

首先近来的时候先设置密码，然后就进入第一个设置页面：

package com.example.safemobile_test;
import com.cbd.pagechange.BaseActivity;
import com.cbd.safemobile.BaseSetupWizardActivity;
import com.example.safemobile_test.activity.TheftFirstActivity;
import com.example.safemobile_test.activity.TheftSetUpOkActivity;
import android.app.Activity;
import android.app.AlertDialog;
import android.app.AlertDialog.Builder;

import android.content.Intent;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class TheftPhone extends BaseSetupWizardActivity {
private AlertDialog dialog ;
private SharedPreferences sp;

// @Override
// protected void onCreate(Bundle savedInstanceState) {
//  // TODO Auto-generated method stub
//  super.onCreate(savedInstanceState);
//  
//  
// }

public void showSetPasswordDialog()
{
  AlertDialog.Builder builder = new Builder(this);
  View view = View.inflate(this, R.layout.layout_first_dialog, null);
  dialog = builder.create();
  
  dialog.setView(view, 0, 0, 0, 0);
  dialog.show();
  
  final EditText inputpassword = (EditText) view.findViewById(R.id.et_first_entry_pwd);
  final EditText reinputPassword = (EditText) view.findViewById(R.id.et_first_entry_pwd_confirm);
  Button onclick_ok = (Button) view.findViewById(R.id.bt_first_entry_ok);
  Button onclick_cancel = (Button) view.findViewById(R.id.bt_first_entry_cancle);
  
  
  
  onclick_ok.setOnClickListener(new OnClickListener(){
   @Override
   public void onClick(View arg0) {
    // TODO Auto-generated method stub
    String getInputPass = inputpassword.getText().toString();
    String getreinputPass = reinputPassword.getText().toString();
   
    if((getInputPass.equals(getreinputPass)) && (getInputPass != null && getreinputPass!=null)
      &&!("".equals(getreinputPass) && "".equals(getInputPass)))
    {
     Toast.makeText(getApplicationContext(), "密码已经设置", Toast.LENGTH_SHORT).show();
     Editor editor = sp.edit();
     editor.putString("password", getInputPass);
     editor.putBoolean("ispassword", true);
     editor.commit();
     
     showGetpasswordDialog();
     dialog.dismiss();
     
     TheftPhone.this.finish();
    }else
    {
     Toast.makeText(getApplicationContext(), "密码不匹配或不能为空", Toast.LENGTH_SHORT).show();
    }
   }
   
  });
  
  onclick_cancel.setOnClickListener(new OnClickListener(){
   @Override
   public void onClick(View arg0) {
    // TODO Auto-generated method stub
    Toast.makeText(getApplicationContext(), "取消", Toast.LENGTH_SHORT).show();
    dialog.dismiss();
   
   
   }
  });
}

public void showGetpasswordDialog()
{
  AlertDialog.Builder builder=new Builder(this);
  View view=View.inflate(this, R.layout.layout_normal_dialog, null);
  dialog=builder.create();
  dialog.setView(view,0,0,0,0);
  dialog.show();
  
  Button bt_normal_entry_ok=(Button) view.findViewById(R.id.bt_normal_entry_ok);
     Button bt_normal_entry_cancle=(Button) view.findViewById(R.id.bt_normal_entry_cancle);
     final EditText et_normal_entry_pwd=(EditText) view.findViewById(R.id.et_normal_entry_pwd);
   
     bt_normal_entry_ok.setOnClickListener(new OnClickListener() {
   
    @Override
    public void onClick(View v) {
     // TODO Auto-generated method stub
    String text=et_normal_entry_pwd.getText().toString().trim();
     if(text.equals(sp.getString("password", ""))){
      if(ps.getBoolean("isLock_state", true))
      {
       Intent intent = new Intent(getApplicationContext(), TheftSetUpOkActivity.class);
       startActivity(intent);
      }else
      {
       Toast.makeText(getApplicationContext(), "ps为：" +ps.getBoolean("isLock_state", true) ,
         Toast.LENGTH_SHORT).show();
       Intent intent = new Intent(getApplicationContext(), TheftFirstActivity.class);
       startActivity(intent);
      }
     
      
      dialog.dismiss();
      TheftPhone.this.finish();
     }
    }
   });
      bt_normal_entry_cancle.setOnClickListener(new OnClickListener() {
   
   @Override
   public void onClick(View v) {
    // TODO Auto-generated method stub
     Intent intent = new Intent(getApplicationContext(), MainActivity.class);
    startActivity(intent);
   }
  });
}
@Override
public void setupView() {
  // TODO Auto-generated method stub
  sp = getSharedPreferences("config", Context.MODE_PRIVATE);
  
  if(!sp.getBoolean("ispassword", false))
  {
   this.showSetPasswordDialog();
  }else
  {
   this.showGetpasswordDialog();
  }
  
}
@Override
public void findView() {
  // TODO Auto-generated method stub
  
}
@Override
public void showNext() {
  // TODO Auto-generated method stub
  
}
@Override
public void showPre() {
  // TODO Auto-generated method stub
  
}
}




接下来就可以往下设置了：
