我正在嘗試制作一個應用程序，它顯示用戶選擇的圖像，可以通過雙擊按鈕進行設置。該應用程序確實要求我提供圖像（這很好），但如果沒有調用此 onActivityResult，我不知道如何在 ImageView 上設置它。主要活動：package com.forever.bobby.cheater20;import android.content.ActivityNotFoundException;import android.content.Intent;import android.graphics.Bitmap;import android.net.Uri;import android.provider.MediaStore;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.util.Log;import android.view.GestureDetector;import android.view.MotionEvent;import android.view.View;import android.widget.Button;import android.widget.ImageView;import com.tomerrosenfeld.customanalogclockview.CustomAnalogClock;public class MainActivity extends AppCompatActivity {    private static final int PICK_IMAGE = 100;    Button hiddenOnClickListener;    ImageView img;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        img = findViewById(R.id.imageView);        CustomAnalogClock customAnalogClock = (CustomAnalogClock) findViewById(R.id.analog_clock);        customAnalogClock.setAutoUpdate(true);        hiddenOnClickListener = (Button) findViewById(R.id.touchButtonHidden);        hiddenOnClickListener.setOnClickListener(new DoubleClickListener() {            @Override            public void onSingleClick(View v) {                Log.e ("mPressesOnce -_-","..");            }            @Override            public void onDoubleClick(View v) {                    Log.e ("mPressesTwice -_-","..");                openGallery();            }        });    }    private void openGallery () {        Intent gallery = new Intent(Intent.ACTION_PICK,                            MediaStore.Images.Media.INTERNAL_CONTENT_URI);        startActivityForResult(gallery, 0);    }    @Override    protected void onActivityResult (int requestCode, int resultCode, Intent data) {        super.onActivityResult(requestCode, resultCode,data);        Log.e ("SHould Be Steeted","");
