Android实现支付宝手势密码功能
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。
