Activity中使用Intent實現頁面跳轉與參數的傳遞（轉），activityintent

建立一個FirstAvtivity.java

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. */@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);myButton = (Button) findViewById(R.id.myButton);myButton.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubIntent intent = new Intent();//Intent傳遞參數intent.putExtra("testIntent", "123");intent.setClass(FirstActivity.this, SecondActivity.class);FirstActivity.this.startActivity(intent);}});}}

建立第二個SecondActivity.java

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;@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);setContentView(R.layout.other);//使用Intent對象得到FirstActivity傳遞來的參數Intent intent = getIntent();String value = intent.getStringExtra("testIntent");myTextView = (TextView) findViewById(R.id.myTextView);myTextView.setText(value);}}

兩個Activity都要在AndroidMenifest.xml中註冊
