【移動應(yīng)用開發(fā)技術(shù)】Android中怎么實現(xiàn)Activity跳轉(zhuǎn)操作

Android中怎么實現(xiàn)Activity跳轉(zhuǎn)操作，針對這個問題，這篇文章詳細介紹了相對應(yīng)的分析和解答，希望可以幫助更多想解決這個問題的小伙伴找到更簡單易行的方法。Android中提供一個叫Intent的類來實現(xiàn)屏幕之間的跳轉(zhuǎn)，下面是一個簡單的示例：在應(yīng)用中增加一個Activity（名字為.ForwardTarget），這需要修改AndroidManifest.xml文件，如下：AndroidActivity跳轉(zhuǎn)代碼示例：<

然后在layout中的main加入一個id為leah2的按鈕，另外再創(chuàng)建一個任意的layout（將要跳轉(zhuǎn)到得layout）,我取名為leah2。接下來是兩個類，一個是AndroidForward，另一個是將要跳轉(zhuǎn)到得ForwardTarget，AndroidActivity跳轉(zhuǎn)實現(xiàn)的代碼分別如下：AndroidForw：

package

com.ray.forward;

import

android.app.Activity;

import

android.content.Intent;

import

android.os.Bundle;

import

android.view.View;

import

android.widget.Button;

public

class

androidForward

extends

Activity

{

/**

Called

when

the

activity

is

first

created.

*/

@Override

public

void

onCreate(Bundle

savedInstanceState)

{

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

Button

btn1

=(Button)findViewById(R.id.leah2);

btn1.setOnClickListener(new

View.OnClickListener(){

@Override

public

void

onClick(View

v)

{

Intent

intent

=

new

Intent();

intent.setClass(androidForward.this,

ForwardTarget.class);

startActivity(intent);

finish();//停止當(dāng)前的Activity,如果不寫,則按返回鍵會跳轉(zhuǎn)回原來的Activity

}

});

}

}

package

com.ray.forward;

import

android.app.Activity;

import

android.content.Intent;

import

android.os.Bundle;

import

android.view.View;

import

android.widget.Button;

public

class

androidForward

extends

Activity

{

/**

Called

the

activity

first

created.

*/

@Override

public

void

onCreate(Bundle

savedInstanceState)

{

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

Button

btn1

=(Button)findViewById(R.id.leah2);

btn1.setOnClickListener(new

View.OnClickListener(){

@Override

public

void

onClick(View

v)

{

Intent

intent

=

new

Intent();

intent.setClass(androidForward.this,

ForwardTarget.class);

startActivity(intent);

finish();//停止當(dāng)前的Activity,如果不寫,則按返回鍵會跳轉(zhuǎn)回原來的Activity

}

});

}

}

ForwardTarget：

package

com.ray.forward;

import

android.app.Activity;

import

android.os.Bundle;

public

class

ForwardTarget

extends

Activity{

@Override

protected

void

onCreate(Bundle

savedInstanceState)

{

//

TODO

Auto-generated

method

stub

super.onCreate(savedInstanceState);

setContentView(R.layout.leah2);

}

}

AndroidForw：

package

com.ray.forward;

import

android.app.Activity;

import

android.content.Intent;

import

android.os.Bundle;

import

android.view.View;

import

android.widget.Button;

public

class

androidForward

extends

Activity

{

/**

@Override

public

void

onCreate(Bundle

savedInstanceState)

{

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

Button

btn1

=(Button)findViewById(R.id.leah2);

btn1.setOnClickListener(new

View.OnClickListener(){

@Override

public

void

{

Intent

intent

Intent();

intent.setClass(androidForward.this,

ForwardTarget.class);

startActivity(intent);

finish();//停止當(dāng)前的Activity,如果不寫,則按返回鍵會跳轉(zhuǎn)回原來的Activity

}

});

}

}
