java - 时间广场日历app的实现方法

Question

日历应用程序的链接是 https://github.com/square/android-times-square#usage

我只是想简单地将这个日历应用程序实现到我的项目中，但我遇到了最困难的时期。我将代码放入我的主要 Activity xml 中，就像它告诉我的那样

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.chexity.MainActivity"
tools:ignore="MergeRootFrame" >

<com.squareup.timessquare.CalendarPickerView
    android:id="@+id/calendar_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

</FrameLayout>

并将代码放入我的主要 Activity 的 onCreate

package com.example.chexity;

import java.util.Calendar;
import java.util.Date;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.app.ActionBar;
import android.support.v4.app.Fragment;
import android.app.Activity;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.os.Build;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Calendar nextYear = Calendar.getInstance();
        nextYear.add(Calendar.YEAR, 1);

        CalendarPickerView calendar = (CalendarPickerView) findViewById(R.id.calendar_view);
        Date today = new Date();
        calendar.init(today, nextYear.getTime())
            .withSelectedDate(today);
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {

        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }

    /**
     * A placeholder fragment containing a simple view.
     */
    public static class PlaceholderFragment extends Fragment {

        public PlaceholderFragment() {
        }

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                Bundle savedInstanceState) {
            View rootView = inflater.inflate(R.layout.fragment_main, container, false);
            return rootView;
        }
    }

}

但是我一直在这一行出错

CalendarPickerView calendar = (CalendarPickerView) findViewById(R.id.calendar_view);

还有 init 方法。

说 calendarpickerview 无法解析为类型。我从下载的日历包中导入了库。我不知道出了什么问题。谁能提供任何见解？

我在最高 4.4 和最低 2.2 版本上运行。

您还没有将 CalendarPickerView 导入到 MainActivity.java 文件中。试试这个:

import com.squareup.timessquare.CalendarPickerView;

您的其他导入语句所在的位置。
