因APP增加了钱包功能,所以APP支付是迫在眉睫的事,市场上大多数的支付界面都是大同小异,因此写了下自定义PopupWindow,简单模仿下支付宝,本人也不常用PopupWindow,写的不好,希望大家海涵。

废话不多说,先上效果图

布局直接上代码吧,也不麻烦

我这里用的是十二个Textview做的按钮操作,大家可以尝试用GridView去操作,原理相同,下面再看看JAVA代码

我们先新建类继承PopupWindow,并添加构造器

public class TestPopWindow  extends PopupWindow{    private Context mContext;    public TestPopWindow(Context context){        this.mContext=context;    }}

初始化控件

  public void init(Context context) {        LayoutInflater inflater = LayoutInflater.from(context);        mPopWindow = inflater.inflate(R.layout.popwindow_password, null);        ed1 = mPopWindow.findViewById(R.id.ed1);        ed2 = mPopWindow.findViewById(R.id.ed2);        ed3 = mPopWindow.findViewById(R.id.ed3);        ed4 = mPopWindow.findViewById(R.id.ed4);        ed5 = mPopWindow.findViewById(R.id.ed5);        ed6 = mPopWindow.findViewById(R.id.ed6);        password = new EditText[6];        password[0] = ed1;        password[1] = ed2;        password[2] = ed3;        password[3] = ed4;        password[4] = ed5;        password[5] = ed6;        txt0 = mPopWindow.findViewById(R.id.txt0);        txt1 = mPopWindow.findViewById(R.id.txt1);        txt2 = mPopWindow.findViewById(R.id.txt2);        txt3 = mPopWindow.findViewById(R.id.txt3);        txt4 = mPopWindow.findViewById(R.id.txt4);        txt5 = mPopWindow.findViewById(R.id.txt5);        txt6 = mPopWindow.findViewById(R.id.txt6);        txt7 = mPopWindow.findViewById(R.id.txt7);        txt8 = mPopWindow.findViewById(R.id.txt8);        txt9 = mPopWindow.findViewById(R.id.txt9);        txtBack = mPopWindow.findViewById(R.id.txtBack);        txtBack.setText("<<-");        txtFinish = mPopWindow.findViewById(R.id.txtFinish);        fotPassword = mPopWindow.findViewById(R.id.fotPassword);        txt0.setOnClickListener(this);        txt1.setOnClickListener(this);        txt2.setOnClickListener(this);        txt3.setOnClickListener(this);        txt4.setOnClickListener(this);        txt5.setOnClickListener(this);        txt6.setOnClickListener(this);        txt7.setOnClickListener(this);        txt8.setOnClickListener(this);        txt9.setOnClickListener(this);        txtBack.setOnClickListener(this);        txtFinish.setOnClickListener(this);        fotPassword.setOnClickListener(this);    }

然后设置PopupWindow,如窗口大小,动画效果等等

   public void setmPopWindow() {        // 把View添加到PopWindow中        this.setContentView(mPopWindow);        //设置SelectPicPopupWindow弹出窗体的宽        this.setWidth(ViewGroup.LayoutParams.MATCH_PARENT);        //设置SelectPicPopupWindow弹出窗体的高        this.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT);        //  设置SelectPicPopupWindow弹出窗体可点击        this.setFocusable(true);        //  设置SelectPicPopupWindow弹出窗体动画效果        this.setAnimationStyle(R.style.mypopwindow_anim_style);        //   设置背景透明        this.setBackgroundDrawable(new ColorDrawable(0x00000000));    }

重写点击事件

 @Override    public void onClick(View view) {        switch (view.getId()) {            case R.id.fotPassword:                Toast.makeText(mContext, "忘记密码", Toast.LENGTH_SHORT).show();                break;            case R.id.txt1:                getJudge(1);                break;            case R.id.txt2:                getJudge(2);                break;            case R.id.txt3:                getJudge(3);                break;            case R.id.txt4:                getJudge(4);                break;            case R.id.txt5:                getJudge(5);                break;            case R.id.txt6:                getJudge(6);                break;            case R.id.txt7:                getJudge(7);                break;            case R.id.txt8:                getJudge(8);                break;            case R.id.txt9:                getJudge(9);                break;            case R.id.txtBack:               //增加判断,看是否清除完毕,防止数组越界                if (currentIndex - 1 >= -1) {                    password[currentIndex--].setText("");                }                break;            case R.id.txt0:                getJudge(1);                break;            case R.id.txtFinish:                Toast.makeText(mContext, getStrPassword(), Toast.LENGTH_SHORT).show();                break;            default:                break;        }    }   /***     * 增加判断,看是否输入够6位,防止数组越界     * @param num     */    private void getJudge(int num) {        if (currentIndex >= -1 && currentIndex < 5) {            password[++currentIndex].setText(num + "");        }    }

最后设置监听,当密码达到第六位时调用接口达成支付

    /**     * 设置监听方法,在第6位输入完成后触发     */    public void setOnFinishInput(final OnPasswordInputFinish passwordInputFinish) {        password[5].addTextChangedListener(new TextWatcher() {            @Override            public void beforeTextChanged(CharSequence s, int start, int count, int after) {            }            @Override            public void onTextChanged(CharSequence s, int start, int before, int count) {            }            @Override            public void afterTextChanged(Editable s) {                if (s.toString().length() == 1) {                    //每次触发都要先将strPassword置空,再重新获取,避免由于输入删除再输入造成混乱                    strPassword = "";                    for (int i = 0; i < 6; i++) {                        strPassword += password[i].getText().toString().trim();                    }                }                passwordInputFinish.inputFinish();            }        });    }

最后调用

public class MainActivity extends AppCompatActivity {    private TextView mtest;    private TestPopWindow mPopupWindow;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        mtest = (TextView) findViewById(R.id.test);        mtest.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                mPopupWindow = new TestPopWindow(MainActivity.this);                mPopupWindow.showAtLocation(MainActivity.this.findViewById(R.id.testsss), Gravity.BOTTOM | Gravity                        .CENTER_HORIZONTAL, 0, 0);                darkenBackground(0.8f);                mPopupWindow.setOnDismissListener(new PopupWindow.OnDismissListener() {                    @Override                    public void onDismiss() {                        darkenBackground(1f);                    }                });                //添加密码输入完成的响应                mPopupWindow.setOnFinishInput(new TestPopWindow.OnPasswordInputFinish() {                    @Override                    public void inputFinish() {                        //输入完成后我们简单显示一下输入的密码                        //也就是说——>实现你的交易逻辑什么的在这里写                        Toast.makeText(MainActivity.this, mPopupWindow.getStrPassword(), Toast.LENGTH_SHORT).show();                    }                });            }        });    }    /**     * 改变背景颜色,灰色     */    private void darkenBackground(Float bgcolor) {        WindowManager.LayoutParams lp = getWindow().getAttributes();        lp.alpha = bgcolor;        getWindow().addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);        getWindow().setAttributes(lp);    }}
