通过bundle对象实现Fragment之间的传值

这里我们介绍一下使用bundle对象进行Fragment传值，比较简单我们直接看代码吧，都有注释的。

MainActivity：

package org.mobiletrain.fragment_demo07;import android.os.Bundle;import android.app.Activity;import android.app.FragmentManager;import android.app.FragmentTransaction;import android.view.Menu;import android.view.View;import android.widget.Toast;public class MainActivity extends Activity {RightFragment fragment;FragmentManager manager;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);fragment = new RightFragment();manager = getFragmentManager();FragmentTransaction transaction = manager.beginTransaction();//通过bundle对象向Fragment传值Bundle bundle = new Bundle();bundle.putString("key", "我是主人，activity");fragment.setArguments(bundle);transaction.add(R.id.rightLayout, fragment);transaction.commit();}public void getRight(View v){//获取从Fragment中传来的值String values = fragment.getArguments().getString("data");Toast.makeText(MainActivity.this, "fragment传来的："+values, 0).show();}}

右边的Fragment：

package org.mobiletrain.fragment_demo07;import android.app.Fragment;import android.os.Bundle;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.Button;import android.widget.Toast;public class RightFragment extends Fragment{@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {// TODO Auto-generated method stubView view = inflater.inflate(R.layout.right, null);//向MainActivity传值getArguments().putString("data", "您好，我是fragment");Button rightButton = (Button)view.findViewById(R.id.rightBn);rightButton.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {//获取从MainActivity传来的值String content = getArguments().getString("key");Toast.makeText(getActivity(),"activity说的："+content, 0).show();}});return view;}}
