android新打开Activity后返回数据.docVIP

首先新建工程这里就不再赘述。 建立两个Activity，OtherActivity向MainActivity返回数据 下面是MainActivity： package com.sharpandroid.many; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.Toast; public class MainActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button nextButton=(Button)findViewById(R.id.next); nextButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub Intent intent=new Intent(); intent.setClass(MainActivity.this, OtherActivity.class); Bundle buddle=new Bundle(); buddle.putString(name, 侯二); buddle.putInt(age, 22); intent.putExtras(buddle); startActivityForResult(intent,1); } }); } protected void onActivityResult(int requestCode,int ResultCode,Intent data){ Toast.makeText(MainActivity.this, data.getStringExtra(name)+data.getIntExtra(age, 1), 3).show(); super.onActivityResult(requestCode, ResultCode, data); } } 下面是OtherActivity package com.sharpandroid.many; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.TextView; public class OtherActivity extends Activity { public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.other); Intent intent=this.getIntent(); Bundle bundle=intent.getExtras(); String name=bundle.getString(name); int age=bundle.getInt(age); TextView paramView=(TextView)findViewById(R.id.other); paramView.setText(名称+name+年龄+age); Button button=(Button)findViewById(R.id.close);
