标签： android

我对android开发很新。我开始创建一个带有片段的导航抽屉我希望调用导航片段形成不同的不同活动我附上了我的代码供您查看。请建议我解决方案。

And this is my fragment which we r calling

package com.example.lunetta;

import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;

public class FragmentTwo extends Fragment {

	ImageView ivIcon;
	TextView tvItemName;

	public static final String IMAGE_RESOURCE_ID = "iconResourceID";
	public static final String ITEM_NAME = "itemName";

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

}



here is my error

3 个答案:

答案 0 :(得分：0)

 Caused by: android.content.ActivityNotFoundException: Unable to find explicit activity class {com.example.lunetta/com.example.lunetta.FragmentTwo}; have you declared this activity in your AndroidManifest.xml?

检查您是否已在清单文件中声明所有活动

答案 1 :(得分：0)

您应该在AndroidManifest.xml中声明所有活动。内部标签应用。像这样：

<activity
        android:name="com.example.gui.SecondActivity"
         android:label="@string/app_name" />

如果活动是您展示的第一个，您应该声明如下：

  <activity
            android:name="com.example.gui.FisrtActivity"
            android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

答案 2 :(得分：0)

从堆栈跟踪：

03-26 12:35:23.261: E/AndroidRuntime(5062):     at com.example.lunetta.Second.aboutUsClick(Second.java:41)

这一行指向：

Fragment fragment = new FragmentTwo();
Intent intent = new Intent(Second.this, FragmentTwo.class);
startActivity(intent);

您无法使用startActivity启动FragmentTwo，因为它是Fragment子类，而不是Activity子类。
