标签：replace method package commit fragment
在最近新学fragment的时候出现了一个错误：
The method replace(int, Fragment) in the type FragmentTransaction is not applicable for the arguments (int, MyFragment) 新建fragment的时候
Fragment newfragment =new MyFragment();
fragmentTransaction.replace(R.layout.activity_main,newfragment ).commit();
提示错误：The method replace(int, Fragment) in the type FragmentTransaction is not applicable for the arguments (int, MyFragment)
错误代码：
package com.example.testforfragment;import android.os.Bundle;import android.app.Activity;import android.app.FragmentManager;import android.app.FragmentTransaction;import android.support.v4.app.Fragment;import android.support.v4.app.Fragment.*;import android.view.Menu;public class MainActivity extends Activity {
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
Fragment newfragment =new MyFragment();
fragmentTransaction.replace(R.layout.activity_main,newfragment ).commit();
}
@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;
}
}
修改：
package com.example.testforfragment;import android.os.Bundle;import android.app.Activity;import android.support.v4.app.Fragment;import android.support.v4.app.FragmentActivity;import android.support.v4.app.FragmentManager;import android.support.v4.app.FragmentTransaction;import android.view.Menu;public class MainActivity extends FragmentActivity {
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
Fragment newfragment =new MyFragment();
fragmentTransaction.replace(R.layout.activity_main,newfragment ).commit();
}
@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;
}
}
在出错的时候一直找不到根源，然后网上找了下，找到了问题所在点，转自http://www.cnblogs.com/1114250779boke/p/3867494.html
