【移動(dòng)應(yīng)用開(kāi)發(fā)技術(shù)】怎么在Android中實(shí)現(xiàn)從Fragment跳轉(zhuǎn)到其他Activity

本文章向大家介紹怎么在Android中實(shí)現(xiàn)從Fragment跳轉(zhuǎn)到其他Activity，主要包括怎么在Android中實(shí)現(xiàn)從Fragment跳轉(zhuǎn)到其他Activity的使用實(shí)例、應(yīng)用技巧、基本知識(shí)點(diǎn)總結(jié)和需要注意事項(xiàng)，具有一定的參考價(jià)值，需要的朋友可以參考一下。Android是一種基于Linux內(nèi)核的自由及開(kāi)放源代碼的操作系統(tǒng)，主要使用于移動(dòng)設(shè)備，如智能手機(jī)和平板電腦，由美國(guó)Google公司和開(kāi)放手機(jī)聯(lián)盟領(lǐng)導(dǎo)及開(kāi)發(fā)。Android——Fragment的靜態(tài)注冊(cè)和動(dòng)態(tài)注冊(cè)為了實(shí)現(xiàn)從Fragment跳轉(zhuǎn)到其他Activity，下面需要?jiǎng)?chuàng)建以下文件：第一步：簡(jiǎn)單編寫(xiě)布局文件fragment_activity.xml和抽象類TemplateFragmentActivity.java代碼如下：fragment_activity.xml<?xml

version="1.0"

encoding="utf-8"?>

<FrameLayout

xmlns:android="/apk/res/android"

android:id="@+id/temp_fragment_activity"

android:layout_width="match_parent"

android:layout_height="match_parent">

</FrameLayout>fragment_activity.xml布局主要用于承載各fragment布局，例如fragment_one.xml和fragment_two.xml。TemplateFragmentActivity.javapackage

com.example.myapplication;

import

android.os.Bundle;

import

androidx.annotation.Nullable;

import

androidx.appcompat.app.AppCompatActivity;

import

androidx.fragment.app.Fragment;

import

androidx.fragment.app.FragmentManager;

import

androidx.fragment.app.FragmentTransaction;

public

abstract

class

TemplateFragmentActivity

extends

AppCompatActivity

{

private

FragmentManager

fm;

private

FragmentTransaction

ts;

private

Fragment

fragment;

//抽象方法，用于創(chuàng)建Fragment實(shí)例

protected

abstract

Fragment

createFragment();

@Override

protected

void

onCreate(@Nullable

Bundle

savedInstanceState)

{

super.onCreate(savedInstanceState);

setContentView(R.layout.fragment_activity);

fm

=

getSupportFragmentManager();

ts

=

fm.beginTransaction();

if

(fragment

==

null){

fragment

=

createFragment();

ts.add(R.id.temp_fragment_activity,fragment);

mit();

}

}

}第二步：分別使類FragmentOneActivity和FragmentTwoActivity繼承類TemplateFragmentActivity并實(shí)現(xiàn)抽象方法createFragment()FragmentOneActivity.javapackage

com.example.myapplication;

import

androidx.fragment.app.Fragment;

public

class

FragmentOneActivity

extends

TemplateFragmentActivity

{

@Override

protected

Fragment

createFragment()

{

return

new

FragmentOne();

}

}FragmentTwoActivity.java與FragmentOneActivity.java類似，不在重復(fù)。第三步：分別編寫(xiě)fragment_one.xml和fragment_two.xml布局文件并通過(guò)編寫(xiě)FragmentOne.java和FragmentTwo.java綁定對(duì)應(yīng)的布局文件，并實(shí)現(xiàn)其具體功能。fragment_one.xml<?xml

version="1.0"

encoding="utf-8"?>

<LinearLayout

xmlns:android="/apk/res/android"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:gravity="center"

android:background="@color/colorPrimaryDark"

android:orientation="vertical">

<TextView

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:gravity="center"

android:text="點(diǎn)擊下面的按鈕跳轉(zhuǎn)到FragmentTwoActivity"

android:textSize="20sp"

android:textAllCaps="false"

android:textColor="#F70505">

</TextView>

<Button

android:id="@+id/btn_fm_one"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="跳轉(zhuǎn)"

android:textSize="30dp"

android:layout_marginTop="20dp">

</Button>

</LinearLayout>fragment_two.xml與fragment_one.xml類似，不在重復(fù)。FragmentOne.javapackage

com.example.myapplication;

import

android.content.Intent;

import

android.os.Bundle;

import

android.view.LayoutInflater;

import

android.view.View;

import

android.view.ViewGroup;

import

import
