android.content.ActivityNotFoundException:找不到处理Intent启动画面的Activity

Question

我遇到了在启动画面后加载新意图的问题.我已经查看了与此例外有关的问题,但他们似乎都处理谷歌游戏或谷歌地图未正确引用的事情,这不是我的情况.

这些是我看过的相关问题

找不到处理意图的活动？

没有找到处理意图的活动

以下是我的清单代码

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.android.main"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="15" />
    <uses-permission android:name="android.permission.INTERNET"/>

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".Splash"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".HomePage"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.HOMEPAGE" />

                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>
        <activity
            android:name=".OrderPlaced"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.ORDERPLACED" />

                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>
    </application>

</manifest>

这是类splash的代码

package com.android.main;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;

public class Splash extends Activity{

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.splash);

        Thread timer = new Thread(){
            public void run(){
                try{
                    sleep(1000);
                }catch(InterruptedException e) {
                    e.printStackTrace();
                }finally{
                    Intent openStartingPoint = new Intent("com.android.main.HOMEPAGE");
                    startActivity(openStartingPoint);
                }
            }
        };
        timer.start();
    }

    @Override
    protected void onPause() {

        super.onPause();
        finish();
    }


}

这是我试图在启动画面后加载的类HomePage

package com.android.main;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.EditText;
import android.widget.Spinner;
import android.widget.TextView;

public class HomePage extends Activity {
    /** Called when the activity is first created. */


    TextView name;
    EditText editName;
    TextView drinks;
    Spinner drinksSpinner;
    TextView message;
    CheckBox checkbox;
    Button createOrderButton;


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        createOrder();
    }

    public void createOrder(){

        createOrderButton = (Button) findViewById(R.id.bCreateOrder);
        createOrderButton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                postInformationtoAPI();

            }

            private void postInformationtoAPI() {

                goToOrderCompleted();
            }

            private void goToOrderCompleted() {
                Intent intent = new Intent(HomePage.this , OrderPlaced.class);
                HomePage.this.startActivity(intent);
                Log.i("onClick", "trying to start new activity to change layout");
            }
        });

    }
}

应用程序强制在加载启动屏幕后退出并提供以下异常

03-14 22:32:33.553: E/AndroidRuntime(3166): android.content.ActivityNotFoundException: No Activity found to handle Intent { act=com.android.main.HOMEPAGE }

任何有关这方面的帮助将不胜感激

Answer 1

你必须区分Intent的构造函数,

 Intent openStartingPoint = new Intent("com.android.main.HOMEPAGE");

假设com.android.main.HOMEPAGE为Intent的动作Filter.这在您的应用程序的android manifest.xml文件中不可用.你有

<action android:name="android.intent.action.HOMEPAGE" />

应该是,

<action android:name="com.android.main.HOMEPAGE" />

或者只是改变它,

Intent openStartingPoint = new Intent(Splash.this, HOMEPAGE.class);
