Android 仿微信支付密码界面

使用

 Bundle bundle = new Bundle();
 bundle.putString(PayFragment.EXTRA_CONTENT, "提现：￥ " + 100.00);
 PayFragment fragment = new PayFragment();
 fragment.setArguments(bundle);
 fragment.setPaySuccessCallBack(MainActivity.this);
 fragment.show(getSupportFragmentManager(), "Pay");

注：如果报getSupportFragmentManager()方法找不到，将Activity继承AppCompatActivity或者FragmentActivity就行
