效果图

项目中使用到了支付密码功能，其实这类界面是比较常用的，涉及支付密码的输入的一般都会用到对的，所以单独地把这部分抽取出来，有需要的朋友可以拿去用哈!

效果就是支付,弹出密码框,输入密码,这个过程密码不可见,并且提供一个输入完毕的监听!

这个弹出层呢,其实就是一个DialogFragment，逻辑封装在其内部

一.弹出层进出动画 (anim文件)

push_bottom_in.xml

<?xml version="1.0" encoding="utf-8"?>
<!-- 上下滑入式 -->
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="200"
        android:fromYDelta="100%p"
        android:toYDelta="0" />
</set>

push_bottom_out.xml

<?xml version="1.0" encoding="utf-8"?>
<!-- 上下滑出式 -->
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="200"
        android:fromYDelta="0"
        android:toYDelta="100%p" />
</set>

二.drawable资源

selector_item_pressed.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/gray_bg" android:state_pressed="true" />
    <item android:drawable="@color/white" android:state_activated="false" />
    <item android:drawable="@color/white" />
</selector>

键盘的点击效果

shape_dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="@android:color/white" />
    <corners android:radius="10dp" />
</shape>

    public static final String EXTRA_CONTENT = "extra_content";      //提示框内容
    public static final String EXTRA_CONTENT2 = "extra_content2";    //提示框内容
    public static final String EXTRA_CONTENT3 = "extra_content3";    //提示框内容

    private PayPassWordView psw_input;
    private PayPassWordView.InputCallBack inputCallBack;

    @NonNull
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // 使用不带Theme的构造器, 获得的dialog边框距离屏幕仍有几毫米的缝隙。
        Dialog dialog = new Dialog(getActivity(), R.style.BottomDialog);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); // 设置Content前设定
        dialog.setContentView(R.layout.fragment_pay);
        dialog.setCanceledOnTouchOutside(true); //外部点击取消
        // 设置宽度为屏宽, 靠近屏幕底部。
        final Window window = dialog.getWindow();
        window.setWindowAnimations(R.style.AnimBottom);
        window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
        final WindowManager.LayoutParams lp = window.getAttributes();
        lp.width = WindowManager.LayoutParams.MATCH_PARENT; // 宽度持平
        lp.gravity = Gravity.TOP;
        window.setAttributes(lp);
        initView(dialog);
        return dialog;
    }

        Bundle bundle = getArguments();

            TextView tv_content2 = (TextView) dialog.findViewById(R.id.tv_content2);
            TextView tv_content3 = (TextView) dialog.findViewById(R.id.tv_content3);
            tv_content.setText(bundle.getString(EXTRA_CONTENT));
            tv_content2.setText(bundle.getString(EXTRA_CONTENT2));

        }
        psw_input = (PayPassWordView) dialog.findViewById(R.id.payPwdView);

        switch (v.getId()) {
            case R.id.iv_close:
                dismiss();
                break;
        }
    }

     */
    public void setPaySuccessCallBack(PayPassWordView.InputCallBack inputCallBack) {

}

十一.逻辑代码中直接引用

public class MainActivity extends AppCompatActivity implements PayPassWordView.InputCallBack, View.OnClickListener {

    private PayFragment fragment;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        findViewById(R.id.btn_pay).setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.btn_pay:
                Bundle bundle = new Bundle();
                bundle.putString(PayFragment.EXTRA_CONTENT, "提现");
                bundle.putString(PayFragment.EXTRA_CONTENT2, "¥" + 1.00);
                bundle.putString(PayFragment.EXTRA_CONTENT3, "额外扣除0.1手续费");
                fragment = new PayFragment();//创建支付弹出框实例
                fragment.setArguments(bundle);//传递信息
                fragment.setPaySuccessCallBack(MainActivity.this);//设置回调
                fragment.show(getSupportFragmentManager(), "Pay");
                break;
        }
    }


    @Override
    public void onInputFinish(String result) {
        Toast.makeText(this, result, Toast.LENGTH_SHORT).show();
        fragment.dismiss();//窗口消失
    }
}

啥都没有,只有一个点击事件而已.

分享结束,这里面的代码可是有我造假的成分哦,不过,我就是喜欢将优秀的东西集成在一起,谢谢观看!!
