Android Activity中使用Intent实现页面跳转与参数传递的方法

package com.zhuguangwei;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;public class FirstActivity extends Activity {  private Button myButton;  /** Called when the activity is first created. */  @Override  public void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.main);    myButton = (Button) findViewById(R.id.myButton);    myButton.setOnClickListener(new OnClickListener() {      @Override      public void onClick(View v) {        // TODO Auto-generated method stub        Intent intent = new Intent();        //Intent传递参数        intent.putExtra("testIntent", "123");        intent.setClass(FirstActivity.this, SecondActivity.class);        FirstActivity.this.startActivity(intent);      }    });  }}

package com.zhuguangwei;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.widget.TextView;public class SecondActivity extends Activity{  private TextView myTextView;  @Override  protected void onCreate(Bundle savedInstanceState) {    // TODO Auto-generated method stub    super.onCreate(savedInstanceState);    setContentView(R.layout.other);    //使用Intent对象得到FirstActivity传递来的参数    Intent intent = getIntent();    String value = intent.getStringExtra("testIntent");    myTextView = (TextView) findViewById(R.id.myTextView);    myTextView.setText(value);  }}
