Android 介面跳轉及資料交換

Android 介面跳轉及資料交換

 

 

本文示範：Android 介面跳轉及資料交換，通過一個小Demo展示全部過程。

效果如下所示：

1）MainActivity.java

 

package doogle.xian.bundletest;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.Menu;import android.view.MenuItem;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.EditText;public class MainActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        Button btn = (Button)findViewById(R.id.btn);        btn.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View arg0) {EditText name = (EditText)findViewById(R.id.name);EditText age = (EditText)findViewById(R.id.age);CData send = new CData(name.getText().toString(),Integer.parseInt(age.getText().toString())); //建立一個Bundle對象Bundle data = new Bundle();data.putSerializable(mydata, send);//建立一個Intent對象Intent intent = new Intent(MainActivity.this,ResultActivity.class);intent.putExtras(data);//啟動Intent對應的ActivitystartActivity(intent);}});    }    @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;    }    @Override    public boolean onOptionsItemSelected(MenuItem item) {        // Handle action bar item clicks here. The action bar will        // automatically handle clicks on the Home/Up button, so long        // as you specify a parent activity in AndroidManifest.xml.        int id = item.getItemId();        if (id == R.id.action_settings) {            return true;        }        return super.onOptionsItemSelected(item);    }}

2）activity_main.xml

 

 

3）ResultActivity.java

 

 

package doogle.xian.bundletest;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.widget.TextView;public class ResultActivity extends Activity {@Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.result);        TextView tv1 = (TextView)findViewById(R.id.tv1);        TextView tv2 = (TextView)findViewById(R.id.tv2);        //獲得啟動該Result的Intent        Intent intent = getIntent();        //直接通過Intent取出它所攜帶的Bundle資料包中的資料        CData accept = (CData)intent.getSerializableExtra(mydata);        tv1.setText(姓名+accept.getName());        tv2.setText(年齡+accept.getAge());    }}

4）result.xml

 

 

5）CData.java

 

 

package doogle.xian.bundletest;import java.io.Serializable;public class CData implements Serializable{private static final long serialVersionUID = 1L;String name;int age;public CData(String n, int a) {name = n;age = a;}public String getName(){return name;}public int getAge(){return age;}}

6）AndroidMainfest.xml
