从另一个项目调用活动

Question

我想将项目 A 调用到项目 B，但在项目 B 中使用项目 C 作为库。

我在项目A中使用了代码

intent = new Intent("com.example.projectb.reading");
        startActivity(intent);

和项目B中的AndroidManifest

<activity 
        android:name="com.example.projectb.reading" 
        android:label="Trainee" 
        android:screenOrientation="portrait">
        <intent-filter>
            <action android:name="com.xample.projecta.cls_show" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
        </activity>

但我有 logcat 是

请帮帮我，问题出在哪里。

Answer 1

请参考 stackoverflow 中的这两个链接。它会帮助你

1. How to call activity of one project from activity of another project in android?Also vice versa?

2。 How to call an activity in another project?

Answer 2

改变

   intent = new Intent("com.example.projectb.reading");
    startActivity(intent);

进入

    intent = new Intent("com.xample.projecta.cls_show");
    startActivity(intent);

Answer 3

你使用了错误的构造函数

intent = new Intent(this, "com.example.projectb.reading");
        startActivity(intent);

阅读intent了解更多信息。

Answer 4

您可以通过Intent-filter 实现这一目标。

FirstActivity

Intent intent = new Intent("com.example.secondapp.SecondActivity");
startActivity(intent);    

SecondActivity - AndroidManifest.xml

    <activity
        android:name="com.example.secondapp.SecondActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="com.example.secondapp.SecondActivity" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
