[Android]放微信支付宝输入框

网上搜索资料后，找到两种比较好的方法，总结如下

方法一：通过自定义view实现

1.1自定义view

public class InputPasswordActivity extends CtmCashActivity implements PassswordInputView.InputCallBack {
    private PassswordInputView mPasswordView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_input_password);
        mPasswordView = (PassswordInputView) findViewById(R.id.text_password);
        mPasswordView.setInputCallBack(this);
    }

    @Override
    public void onInputFinish(String result) {
        Toast.makeText(this, result, Toast.LENGTH_LONG).show();
    }
}

1.2.布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <com.ctm.ctmcash.view.PassswordInputView
        android:id="@+id/text_password"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="20dp"
        android:layout_marginRight="20dp"
        android:layout_marginTop="40dp"
        android:background="@android:color/white"
        app:border_color="@color/password_box_gray"
        app:dot_color="@color/text_dark_gray"></com.ctm.ctmcash.view.PassswordInputView>
</LinearLayout>

1.3.测试activity

public class InputPasswordActivity extends CtmCashActivity implements PassswordInputView.InputCallBack {
    private PassswordInputView mPasswordView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_input_password);
        mPasswordView = (PassswordInputView) findViewById(R.id.text_password);
        mPasswordView.setInputCallBack(this);
    }

    @Override
    public void onInputFinish(String result) {
        Toast.makeText(this, result, Toast.LENGTH_LONG).show();
    }
}
