1.呼叫照相機時通過putExtra的方式直接指定儲存路徑

String FilePath = "/sdcard/pic/";
		
File file = new File(FilePath);
file.mkdirs();// 建立資料夾

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);// 定義呼叫相機並取回圖片的Intent意圖

intent.putExtra(MediaStore.EXTRA_OUTPUT,
		Uri.fromFile(new File(FilePath, "img.jpg"))); // 將圖片儲存到指定的儲存路徑

startActivityForResult(intent, 1);
 

onActivityResult方法

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
	super.onActivityResult(requestCode, resultCode, data);

	if (resultCode == Activity.RESULT_OK) {

		Bitmap bitmap = BitmapFactory.decodeFile(FilePath + imgName);

		ImageView ic = (ImageView) findViewById(R.id.imageView);
	
        	ic.setImageBitmap(bitmap);
			
	} else {
		finish();
	}
}
 

2.在呼叫照相機後在onActivityResul裡儲存圖片

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);// 定義呼叫相機並取回圖片的Intent意圖

startActivityForResult(intent, 1);

onActivityResult方法

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
	super.onActivityResult(requestCode, resultCode, data);

	if (resultCode == Activity.RESULT_OK) {

	    Bitmap bitmap = (Bitmap) data.getExtras().get("data");

            File file = new File("/sdcard/pic/");
            
            file.mkdirs();// 建立資料夾

            String fileName = "/sdcard/pic/img.jpg";

            try {
                b = new FileOutputStream(fileName);

                bitmap.compress(Bitmap.CompressFormat.JPEG, 100, b);// 把資料寫入檔案,其中第一個引數表示圖片格式，
                                                                   //第二個引數指壓縮率。100表示不壓縮
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            } finally {
                try {
                    b.flush();
                    b.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }

            ImageView ic = (ImageView) findViewById(R.id.imageView);
	
            ic.setImageBitmap(bitmap);
			
	} else {
		finish();
	}
}
