第一个Android应用程序错误

Question

我当时正在学习Android教程，当我去运行我的程序时，它给了我一个错误，说“不幸先生先生的应用程序已停止”。我无法弄清楚为什么。

这里是我的错误的logcat：

这里是我的MainActivity：

package com.example.myfirstapp; 

import android.content.Intent; 
import android.os.Bundle; 
import android.support.v7.app.ActionBarActivity; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.view.View; 
import android.widget.EditText; 

public class MainActivity extends ActionBarActivity { 
    public final static String EXTRA_MESSAGE = "com.example.myfirstapp.MESSAGE";@ 
    Override 
    protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    } 


    @ 
    Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.main, menu); 
    return true; 
    } 

    @ 
    Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     // Handle action bar item clicks here. The action bar will 
     // automatically handle clicks on the Home/Up button, so long 
     // as you specify a parent activity in AndroidManifest.xml. 
     int id = item.getItemId(); 
     if (id == R.id.action_settings) { 
     return true; 
     } 
     return super.onOptionsItemSelected(item); 
    } 
    /** Called when the user clicks the Send button */ 
    public void sendMessage(View view) { 
    Intent intent = new Intent(this, DisplayMessageActivity.class); 
    EditText editText = (EditText) findViewById(R.id.edit_message); 
    String message = editText.getText().toString(); 
    intent.putExtra(EXTRA_MESSAGE, message); 
    startActivity(intent); 
    } 
} 

而这里的DisplayMessageActivity：如果

package com.example.myfirstapp; 

import android.content.Intent; 
import android.os.Bundle; 
import android.support.v7.app.ActionBarActivity; 
import android.view.MenuItem; 
import android.widget.TextView; 

public class DisplayMessageActivity extends ActionBarActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     // Get the message from the intent 
     Intent intent = getIntent(); 
     String message = intent.getStringExtra(MainActivity.EXTRA_MESSAGE); 

     // Create the text view 
     TextView textView = new TextView(this); 
     textView.setTextSize(40); 
     textView.setText(message); 

     // Set the text view as the activity layout 
     setContentView(textView); 

    } 
    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     // Handle action bar item clicks here. The action bar will 
     // automatically handle clicks on the Home/Up button, so long 
     // as you specify a parent activity in AndroidManifest.xml. 
     int id = item.getItemId(); 
     if (id == R.id.action_settings) { 
      return true; 
     } 
     return super.onOptionsItemSelected(item); 
    } 
} 

不知道需要什么都重要。

Answer 1

您可以在误差在日志中看到：

09-24 23:17:05.280: E/AndroidRuntime(691): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.myfirstapp/com.example.myfirstapp.MainActivity}: android.util.AndroidRuntimeException: **You cannot combine swipe dismissal and the action bar.** 

不能同时使用刷卡解雇和操作栏。

消除其中一个功能，它将运行。

干杯！
