Android实现支付宝手势密码功能

本文主要是介绍Android实现支付宝手势密码功能,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

今天就给大家分享android实现支付宝手势密码,很常见,像现在用微信支付,支付宝支付的时候都要自己设置的4位PIN码,然后输入PIN码后立即调用支付接口去支付,毫无疑问的安全问题,不会觉得手机被人拿了后却不知道自己网银的钱的去向,这也是正常安全逻辑性问题。

好,下面我们来看下具体的实现:

入口,启动页面就简单的几个按钮,布局贴出来,代码如下:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
>


 <LinearLayout
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:layout_marginTop="20dp"
  android:orientation="horizontal">

 <Button
  android:id="@+id/button_enable_pin"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:text="设置" />

 <Button
  android:id="@+id/button_change_pin"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:layout_below="@+id/button_enable_pin"
  android:text="改变" />

 <Button
  android:id="@+id/button_unlock_pin"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:layout_below="@+id/button_change_pin"
  android:text="检验" />

 <Button
  android:id="@+id/button_compat_locked"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:layout_below="@+id/button_unlock_pin"
  android:text="PIN页面" />

 </LinearLayout>
</RelativeLayout>

我们看下四个按钮的操作的事情,代码如下:

package com.github.orangegangsters.lollipin;

import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Toast;
import com.github.orangegangsters.lollipin.lib.PinActivity;
import com.github.orangegangsters.lollipin.lib.managers.AppLock;

import lollipin.orangegangsters.github.com.lollipin.R;

/**
 * Created by laiyingtang on 2016/06/21.
 */
public class MainActivity extends PinActivity implements View.OnClickListener {

 private static final int REQUEST_CODE_ENABLE = 11;

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

  this.findViewById(R.id.button_enable_pin).setOnClickListener(this);
  this.findViewById(R.id.button_change_pin).setOnClickListener(this);
  this.findViewById(R.id.button_unlock_pin).setOnClickListener(this);
  this.findViewById(R.id.button_compat_locked).setOnClickListener(this);

 }

 /**
  * 四个按钮的点击处理
  * @param v
  */
 @Override
 public void onClick(View v) {
  Intent intent = new Intent(MainActivity.this, CustomPinActivity.class);
  switch (v.getId()) {
   //设置密码
   case R.id.button_enable_pin:
    intent.putExtra(AppLock.EXTRA_TYPE, AppLock.ENABLE_PINLOCK);
    startActivityForResult(intent, REQUEST_CODE_ENABLE);
    break;
   //改变密码
   case R.id.button_change_pin:
    intent.putExtra(AppLock.EXTRA_TYPE, AppLock.CHANGE_PIN);
    startActivity(intent);
    break;
   //校验密码
   case R.id.button_unlock_pin:
    intent.putExtra(AppLock.EXTRA_TYPE, AppLock.UNLOCK_PIN);
    startActivity(intent);
    break;
   //填入手势密码进入PIN页面
   case R.id.button_compat_locked:
    Intent intent2 = new Intent(MainActivity.this, LockedCompatActivity.class);
    startActivity(intent2);
    break;

  }
 }
 //回调
 @Override
 protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  super.onActivityResult(requestCode, resultCode, data);
  switch (requestCode){
   case REQUEST_CODE_ENABLE:
    Toast.makeText(this, "启用PIN码", Toast.LENGTH_SHORT).show();
    break;
  }
 }
}

都看的明白,以下会把CustomPinActivity,LockedCompatActivity贴出来,前面的操作大概就是这样,分别给每个按钮设置不同的putExtra值,第一个设置按钮利用的是startActivityForResult启动页面,因为设置完密码后是存入到Appcation中的,而且拿到请求码回到主页面的时候,吐司了“启动PIN码”,但是你想改变和检验密码必须要先设置密码,这是很正常的逻辑,我把Appcation先贴出来,比较简单,几句代码:

package com.github.orangegangsters.lollipin;

import android.app.Application;


import com.github.orangegangsters.lollipin.lib.managers.LockManager;

import lollipin.orangegangsters.github.com.lollipin.R;

/**
 * Created by laiyingtang on 2016/06/21.
 */
public class CustomApplication extends Application {

 @SuppressWarnings("unchecked")
 @Override
 public void onCreate() {
  super.onCreate();

  LockManager<CustomPinActivity> lockManager = LockManager.getInstance();
  lockManager.enableAppLock(this, CustomPinActivity.class);
  lockManager.getAppLock().setLogoId(R.drawable.security_lock);
 }
}

LockManager是采用网友的Library。下面我把CustomPinActivity贴出来:

package com.github.orangegangsters.lollipin;

import android.content.res.Resources;
import android.graphics.Color;
import android.graphics.Typeface;
import android.graphics.drawable.ColorDrawable;
import android.widget.Toast;
import com.github.orangegangsters.lollipin.lib.managers.AppLockActivity;
import lollipin.orangegangsters.github.com.lollipin.R;
import uk.me.lewisdeane.ldialogs.BaseDialog;
import uk.me.lewisdeane.ldialogs.CustomDialog;

/**
 * 对话框页面
 * Created by laiyingtang on 2016/06/21.
 */
public class CustomPinActivity extends AppLockActivity {

 @Override
 public void showForgotDialog() {
  Resources res = getResources();
  //创建对话框
  CustomDialog.Builder builder = new CustomDialog.Builder(this,
    res.getString(R.string.activity_dialog_title),
    res.getString(R.string.activity_dialog_accept));
  builder.content(res.getString(R.string.activity_dialog_content));
  builder.negativeText(res.getString(R.string.activity_dialog_decline));

  //设置样式
  builder.darkTheme(false);
  builder.typeface(Typeface.SANS_SERIF);
  builder.positiveColor(res.getColor(R.color.light_blue_500)); // 设置按钮的字体颜色(确定)
  builder.negativeColor(res.getColor(R.color.light_blue_500));// 设置按钮的字体颜色(取消)
  builder.rightToLeft(false); // 按钮是否从左到右的顺序排列
  builder.titleAlignment(BaseDialog.Alignment.CENTER);//居中
  builder.buttonAlignment(BaseDialog.Alignment.CENTER);
  builder.setButtonStacking(false);

  //设置字体的大小
  builder.titleTextSize((int) res.getDimension(R.dimen.activity_dialog_title_size));
  builder.contentTextSize((int) res.getDimension(R.dimen.activity_dialog_content_size));
  builder.positiveButtonTextSize((int) res.getDimension(R.dimen.activity_dialog_positive_button_size));
  builder.negativeButtonTextSize((int) res.getDimension(R.dimen.activity_dialog_negative_button_size));

  //创建对话框
  CustomDialog customDialog = builder.build();
  customDialog.setCanceledOnTouchOutside(false);
  customDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));//透明
  customDialog.setClickListener(new CustomDialog.ClickListener() {
   @Override
   public void onConfirmClick() {
    Toast.makeText(getApplicationContext(), "Yes", Toast.LENGTH_SHORT).show();
   }

   @Override
   public void onCancelClick() {
    Toast.makeText(getApplicationContext(), "Cancel", Toast.LENGTH_SHORT).show();
   }
  });

  //显示对话框
  customDialog.show();
 }

 @Override
 public void onPinFailure(int attempts) {

 }

 @Override
 public void onPinSuccess(int attempts) {

 }

 @Override
 public int getPinLength() {
  return super.getPinLength();//可重修修改默认的长度
 }
}

CustomDialog也是用第三方,而没有用系统自带的AlertDialog,因为太丑了,想我这种追求完美的,都是丑拒的。设置密码的view是自定义的,包括Keyboard。

LockedCompatActivity类如下:

package com.github.orangegangsters.lollipin;

import android.os.Bundle;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.widget.ImageView;
import android.widget.Toast;

import com.github.orangegangsters.lollipin.lib.PinCompatActivity;

import lollipin.orangegangsters.github.com.lollipin.R;

/**
 * PIN页面
 * Created by laiyingtang on 2016/06/21.
 */
public class LockedCompatActivity extends PinCompatActivity {

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

 private void initView() {
  Toolbar toolbar = (Toolbar) findViewById(R.id.id_toolbar);
  ImageView iv_image= (ImageView) findViewById(R.id.iv_image);
  setSupportActionBar(toolbar);

  toolbar.setTitle("Title");
  toolbar.setTitleTextColor(getResources().getColor(android.R.color.white));
  toolbar.setSubtitleTextColor(getResources().getColor(android.R.color.white));
  toolbar.setLogo(R.drawable.ic_launcher);
  iv_image.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View v) {
    Toast.makeText(LockedCompatActivity.this,"可继续做相应的操作",Toast.LENGTH_SHORT).show();
   }
  });
 }
}

该类是输入正确的PIN码后才能访问的页面,从而在该页面可以操作你想操作的东西,比如调用支付接口,直接执行支付操作,这也是一个不错的例子。错误的PIN码振动Keyboard。
