Explicit Intents-Android

目標是從編輯視圖中獲取文本，並在單擊按鈕的其他Activity中將其顯示在TextView中。我的問題：只要我點擊按鈕應用程序停止。Explicit Intents-Android

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")); 
    } 
}

可以發佈XML佈局也 – Raghunandan

爲什麼你又在問同一個問題，http://stackoverflow.com/questions/21995813/explicit-intents-in-android – InnocentKiller

請你添加一個堆棧跟蹤？ – donfuxx

android.content.ActivityNotFoundException：無法找到顯式的活動類 {com.satish.explicitintents/com.satish.explicitintents.Second};你有在你的AndroidManifest.xml中聲明瞭這個活動嗎？

stacktrace表明您尚未在清單中聲明該活動。

你開了包的名字拼錯了

更改爲

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

檢查

package="com.satish.explicitintents"

或者只是

<activity android:name=".Second"

Thanx很多傢伙.. :) – SAtish

@ user3338306因爲你是新的。請閱讀這個http://meta.stackexchange.com/questions/5234/how-does-accepting-an-answer-work – Raghunandan

的問題是在你的清單文件。更換以下線 -

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

與 -

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

你包的名字是錯的。

指定第二個活動的路徑時，您在清單文件中有錯誤。您需要使用：

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