명시 적 의도 - Android

Question

목표는 편집보기에서 텍스트를 가져와 버튼을 클릭하면 다른 활동의 TextView에 표시하는 것입니다. 내 문제 : 버튼을 클릭하자마자 애플리케이션이 멈 춥니 다.

Main.java :

package com.satish.explicitintents; 

import android.os.Bundle; 
import android.app.Activity; 
import android.content.Intent; 
import android.view.Menu; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.Button; 
import android.widget.EditText; 

public class Main extends Activity { 

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

     final EditText et = (EditText) findViewById(R.id.editText1); 

     Button b = (Button) findViewById(R.id.button1); 
     b.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      Intent intent =new Intent(Main.this, Second.class); 
      intent.putExtra("thetext", et.getText().toString()); 
      startActivity(intent); 
     } 
    }); 
    } 
} 

Second.java :

package com.satish.explicitintents; 

import android.app.Activity; 
import android.os.Bundle; 
import android.widget.TextView; 

public class Second extends Activity { 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.second); 

     TextView tv = (TextView) findViewById(R.id.textView1); 
     tv.setText(getIntent().getExtras().getString("thetext")); 
    } 
}

Answer 1

android.content.ActivityNotFoundException : 명시 적으로 활동 등급을 찾을 수 없습니다. {com.satish.explicitintents/com.satish.explicitintents.Second}; 당신의 AndroidManifest.xml에서이 활동을 선언하셨습니까?

stacktrace는 매니페스트에서 활동을 선언하지 않았 음을 나타냅니다.

당신은

<activity android:name="com.satish.explicitintents.Second" 
//explicitintents not explicitintent 

확인

package="com.satish.explicitintents" 

또는 문제는 매니페스트 파일에 바로

<activity android:name=".Second" 

Answer 2

에 패키지 이름을 잘못

변경을 얻었다. 다음과 같은 라인 -

<activity android:name="com.satish.explicitintent.Second" 
    android:label="@string/app_name"/> 

뿐인데

<activity android:name="com.satish.explicitintents.Second" 
      android:label="@string/app_name"/> 

패키지 이름이 잘못 교체합니다.

Answer 3

두 번째 활동의 경로를 지정하는 동안 매니페스트 파일에 오류가 있습니다. 당신은 사용할 필요가 : 다시 같은 질문을하는 이유는

<activity android:name="com.satish.explicitintents.Second" 
      android:label="@string/app_name"/>
