Android手势密码--设置和校验功能的实现代码

效果图如下，大家感觉不错请参考实现代码

具体代码如下所示：

private void setGesturePassword() {
 toggleMore.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
  @Override
  public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
   if (isChecked) {
//     UIUtils.toast("开启了手势密码", false);
//     sp.edit().putBoolean("isOpen", true).commit();
    String inputCode = sp.getString("inputCode", "");
    if (TextUtils.isEmpty(inputCode)) {//之前没有设置过
     new AlertDialog.Builder(MoreFragment.this.getActivity())
       .setTitle("设置手势密码")
       .setMessage("是否现在设置手势密码")
       .setPositiveButton("确定", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
         UIUtils.toast("现在设置手势密码", false);
         sp.edit().putBoolean("isOpen", true).commit();
//           toggleMore.setChecked(true);
         //开启新的activity:
         ((BaseActivity) MoreFragment.this.getActivity()).goToActivity(GestureEditActivity.class, null);
        }
       })
       .setNegativeButton("取消", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
         UIUtils.toast("取消了现在设置手势密码", false);
         sp.edit().putBoolean("isOpen", false).commit();
         toggleMore.setChecked(false);
        }
       })
       .show();
    } else {
     UIUtils.toast("开启手势密码", false);
     sp.edit().putBoolean("isOpen", true).commit();
//      toggleMore.setChecked(true);
    }
   } else {
    UIUtils.toast("关闭了手势密码", false);
    sp.edit().putBoolean("isOpen", false).commit();
//     toggleMore.setChecked(false);
   }
  }
 });
}
private void resetGesture() {
 tvMoreReset.setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View v) {
   boolean checked = toggleMore.isChecked();
   if (checked) {
    ((BaseActivity) MoreFragment.this.getActivity()).goToActivity(GestureEditActivity.class, null);
   } else {
    UIUtils.toast("手势密码操作已关闭，请开启后再设置", false);
   }
  }
 });
}
