在片段中創建按鈕

你好我是android新手我想問我如何在片段布局中做意圖

任何答案我都會非常感激

這是代碼：

對于 HomeFragment.java

package com.example.splashscreen;

import android.annotation.SuppressLint;

import android.content.Intent;
import android.net.Uri;
import android.net.wifi.hotspot2.pps.HomeSp;
import android.os.Bundle;

import androidx.fragment.app.Fragment;
import androidx.fragment.app.FragmentActivity;
import androidx.fragment.app.FragmentManager;
import androidx.fragment.app.FragmentTransaction;

import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.ListView;

import com.denzcoskun.imageslider.ImageSlider;
import com.denzcoskun.imageslider.constants.ScaleTypes;
import com.denzcoskun.imageslider.models.SlideModel;

import java.util.ArrayList;
import java.util.List;

/**
 * A simple {@link Fragment} subclass.
 * Use the {@link HomeFragment#newInstance} factory method to
 * create an instance of this fragment.
 */
public class HomeFragment extends Fragment implements View.OnClickListener {
    // Initiate
    Button button;
    View rootView;

    // TODO: Rename parameter arguments, choose names that match
    // the fragment initialization parameters, e.g. ARG_ITEM_NUMBER
    private static final String ARG_PARAM1 = "param1";
    private static final String ARG_PARAM2 = "param2";

    // TODO: Rename and change types of parameters
    private String mParam1;
    private String mParam2;

    public HomeFragment() {
        // Required empty public constructor
    }

    /**
     * Use this factory method to create a new instance of
     * this fragment using the provided parameters.
     *
     * @param param1 Parameter 1.
     * @param param2 Parameter 2.
     * @return A new instance of fragment HomeFragment.
     */
    // TODO: Rename and change types and number of parameters
    public static HomeFragment newInstance(String param1, String param2) {
        HomeFragment fragment = new HomeFragment();
        Bundle args = new Bundle();
        args.putString(ARG_PARAM1, param1);
        args.putString(ARG_PARAM2, param2);
        fragment.setArguments(args);
        return fragment;
    }

    @SuppressLint("WrongViewCast")
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        /**Button btnMoveActivity = (Button) rootView.findViewById(R.id.btn1);
        btnMoveActivity.setOnClickListener((View.OnClickListener) this);

         ImageSlider imageSlider = getActivity().findViewById(R.id.image_slider);

        List<SlideModel> slideModel=new ArrayList<>();
        slideModel.add(new SlideModel(R.drawable.kucing2, ScaleTypes.FIT));
        slideModel.add(new SlideModel(R.drawable.kucing1,ScaleTypes.FIT));
        slideModel.add(new SlideModel(R.drawable.kucing2,ScaleTypes.FIT));

        imageSlider.setImageList(slideModel,ScaleTypes.FIT);
**/

        if (getArguments() != null) {
            mParam1 = getArguments().getString(ARG_PARAM1);
            mParam2 = getArguments().getString(ARG_PARAM2);
        }
    }
    
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        rootView = inflater.inflate(R.layout.fragment_home, container, false);
        return inflater.inflate(R.layout.fragment_home, container, false);
    }



    public void onViewCreated(View view,Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        button = (Button) rootView.findViewById(R.id.btn1);

        button.setOnClickListener(view1 -> {
            switch (view1.getId()){
                case R.id.btn1:
                    Intent moveIntent = new Intent(MainActivity.this,MoveActivity.class); // my button isn't working here
                    startActivity(moveIntent);
                    break;
                }
            });
}

    @Override
    public void onClick(View view) {

    }
}

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.splashscreen">

    <uses-permission android:name="android.permission.INTERNET"/>

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme.Splashscreen">
        <activity
            android:name=".Splashscreen"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".MainActivity">
        </activity>
    </application>

</manifest>

我的按鈕無法執行意圖，我嘗試了幾種我無法理解的方法我想稍后添加影像滑塊，但我更喜歡先使用按鈕

謝謝你的寶貴回答

uj5u.com熱心網友回復：

我不確定這是否適用于您的情況，但如果您想訪問fragment's主機活動并使用它，Intent您可以試試這個

Activity myParentActivity = (MainActivity) getActivity();
Intent moveIntent = new Intent(myParentActivity, MoveActivity.class);

或這個

Activity myParentActivity = (MainActivity) requireActivity();
Intent moveIntent = new Intent(myParentActivity, MoveActivity.class);

把這個放在你的AndroidManifest.xml

<activity android:name=".MoveActivity"/>
