首先我在對應的主頁面 xml裡面進行一個相關的UI介面的佈局

對應的兩個Button按鈕 一個拍照，一個呼叫相簿

一個Imageview 的一張小機器人的圖片

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context="com.example.shangchuantouxiang.MainActivity">

  <!--  <com.facebook.drawee.view.SimpleDraweeView
        android:id="@+id/img"
        android:layout_width="100dp"
        android:layout_height="100dp"
        fresco:placeholderImage="@mipmap/ic_launcher"
        fresco:placeholderImageScaleType="focusCrop"
        fresco:roundAsCircle="true"
        />-->
    <ImageView
       android:src="@mipmap/ic_launcher"
        android:id="@+id/img"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
<Button
    android:text="拍照"
    android:id="@+id/paizhao"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />
    <Button
        android:text="相簿"
        android:id="@+id/xc"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />
</LinearLayout>
 

對應的佈局的兩個按鈕           拍照       和 相簿     的點選事件     

public class MainActivity extends AppCompatActivity {
    Button paizhao, xc;
    ImageView img;
//定義一個私有的變數來拍照回撥
        private String path;
    //定義靜態變數來記錄相簿
    private static final int IMAGE = 1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        img = (ImageView) findViewById(R.id.img);
        paizhao = (Button) findViewById(R.id.paizhao);
        xc = (Button) findViewById(R.id.xc);

     paizhao.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        //第一種
//	 Intent intent = new Intent("android.media.action.STILL_IMAGE_CAMERA");
//	 startActivity(intent);
//  filePath = "storage/emulated/legacy/"+System.currentTimeMillis()+".jpg";
        path= Environment.getExternalStorageDirectory().getPath()+"/"+System.currentTimeMillis()+".jpg";

        Uri uri=Uri.fromFile(new File(path));//處理存放位置
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);//建立拍照的意圖
        intent .putExtra(MediaStore.EXTRA_OUTPUT, uri);//指定處理方的位置為系統的沼澤的存放位置
        startActivityForResult(intent, 1);
    }
});


        //呼叫相簿的相片回傳
        xc.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                startActivityForResult(intent,IMAGE);

            }
        });


    }
// 進行的相簿裡面來獲得code來判斷         //呼叫相簿
    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        //       呼叫相機拍照  把相機拍的照傳回 該圖片的控制元件
        Uri uri = Uri.fromFile(new File(path));
        img.setImageURI(uri);
        //獲取圖片路徑
        if (requestCode == IMAGE && resultCode == Activity.RESULT_OK && data != null) {
            Uri selectedImage = data.getData();
            String[] filePathColumns = {MediaStore.Images.Media.DATA};
            Cursor c = getContentResolver().query(selectedImage, filePathColumns, null, null, null);
            c.moveToFirst();
            int columnIndex = c.getColumnIndex(filePathColumns[0]);
            String imagePath = c.getString(columnIndex);
            showImage(imagePath);
            c.close();

        }
    }



    private void showImage(String imaePath) {

        Bitmap bm = BitmapFactory.decodeFile(imaePath);

        img.setImageBitmap(bm);

    }

}
