Question

好的，所以我已经克服了很多错误，只是因为我的应用程序崩溃了我试图访问我的第二个Activity。错误指向我的第二个活动的类，它位于布局类的内部。我试图在src中创建我的第二个活动类，但Android Studio似乎不想让我。有没有其他人遇到过这个问题，你有建议吗？谢谢。这是我的第二个活动的代码，以及我的AndroidManifest。

package com.example.friendlistcleaner.app;


import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;

public class facebookhandler extends ActionBarActivity
{


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

    // 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 onCreateOptionsMenu(Menu menu) {

    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.facebookhandler, 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);
}

}

Answer 1

我的猜测是你不应该在布局中创建Activity。如果您在src文件夹下使用Android Studio，请右键单击包名称。然后选择＆＃34; New＆＃34; - ＆GT; ＆＃34;活动＆＃34;等等 http://i57.tinypic.com/nezs5g.png
