跟选择银行卡界面类似，也是用一个PopupWindow,不过输入密码界面是一个自定义view，当输入六位密码完成后用回调在Activity中获取到输入的密码并以Toast显示密码。效果图如下：

自定义view布局效果图及代码如下：

PopupWindow中直接使用该控件

<"1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent"> <com.example.zhpan.mypayui.PayView android:id="@+id/pv_pop_win" android:layout_width="match_parent" android:layout_height="match_parent"/> </LinearLayout>

MainActivity中显示PupupWindow

public class MainActivity extends AppCompatActivity implements View.OnClickListener { private TextView mTextView; private PopupWindow mPopupWindow; private View popView; private PayView mPayView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); initView(); setListener(); } private void initView() { mTextView = (TextView) findViewById(R.id.tv_main_pay); } private void setListener() { mTextView.setOnClickListener(this); } // 显示弹窗 public void showPopupWindow() { // 初始化弹窗 popView = View.inflate(this, R.layout.pop_window, null); mPopupWindow = new PopupWindow(popView, ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT); mPayView = (PayView) popView.findViewById(R.id.pv_pop_win); mPayView.getTitle().setText("选择到账银行卡"); // 设置动画 mPopupWindow.setAnimationStyle(R.style.popwin_anim_style); mPopupWindow.showAsDropDown(findViewById(R.id.ll_main), 0, 0); mPopupWindow.setOutsideTouchable(true); mPayView.setOnFinishInput(new OnPasswordInputFinish() { @Override public void inputFinish() { Toast.makeText(MainActivity.this, mPayView.getPassword(), Toast.LENGTH_SHORT).show(); } }); mPayView.getCancel().setOnClickListener(this); mPayView.getForgetPsw().setOnClickListener(this); } @Override public void onClick(View v) { switch (v.getId()) { case R.id.tv_main_pay: showPopupWindow(); break; case R.id.iv_pay_back: mPopupWindow.dismiss(); break; case R.id.tv_pay_forgetPwd: Toast.makeText(MainActivity.this,"忘记密码",Toast.LENGTH_SHORT).show(); break; } } }
