我正在制作自定义列表视图，其中我必须添加用户从 sd 卡或相机拍摄的图像。为此，我拍摄一个图像视图和两个按钮。一个按钮从相机拍摄照片，另一个按钮从sd 卡拍摄，然后他们添加图像视图中的图片..现在当我在自定义列表视图中传递该图像 uri 时，第一次添加图像，但第二次应用程序崩溃....如果有人知道答案，请发布它。提前致谢！！

这是代码。这是用于按钮单击..

camera.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {

                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(
                        Environment.getExternalStorageDirectory(), "temp.jpg")));
                startActivityForResult(intent, 2);

            }
        });

        sdcard.setOnClickListener(new Button.OnClickListener() {

            @Override
            public void onClick(View v) {

                Intent i = new Intent(
                        Intent.ACTION_PICK,
                        android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI);

                startActivityForResult(i, 0);

            }
        });

        adapter = new SimpleAdapter(
                this,
                list12,
                R.layout.list_row_1,
                new String[] { "name", "address", "location", "image" },
                new int[] { R.id.name, R.id.address, R.id.location, R.id.image });

        setListAdapter(adapter);

在这之后..

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

        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == 2) {
            File picture = new File(Environment.getExternalStorageDirectory()
                    + "/temp.jpg");

            imgUri = Uri.fromFile(picture);
            targetImage.setImageURI(imgUri);
            location1 = "Camera";
        }

        else {
            if (resultCode == RESULT_OK) {
                targetUri = data.getData();
                textTargetUri.setText(targetUri.toString());
                try {
                    bitmap = BitmapFactory.decodeStream(getContentResolver()
                            .openInputStream(targetUri));

                    //decodeBitmap(bitmap, 4, 4);

                    targetImage.setImageBitmap(bitmap);
                    location1 = "Sd card";

                } catch (FileNotFoundException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }

        }

然后我在列表视图中添加图像

private void populateList() {

    HashMap<String, Object> temp11 = new HashMap<String, Object>();
    name1 = textname.getText().toString();
    address1 = textaddress.getText().toString();


    if (name1.equals("") || address1.equals("")) {
        String str = "Don't Leave field blank !";
        Toast toast = Toast.makeText(LastPage.this,

        str, Toast.LENGTH_SHORT);
        toast.setGravity(Gravity.CENTER, 0, 0);
        toast.show();
    }

    else if (location1 == "Sd card") {

        textname.setText("");
        textaddress.setText("");
        temp11.put("name", name1);
        temp11.put("address", address1);

        temp11.put("location", location1);

        temp11.put("image", targetUri);
        targetImage.setImageBitmap(null);
        list12.add(0, temp11);
        adapter.notifyDataSetChanged();
    } else if (location1 == "Camera") {

        textname.setText("");
        textaddress.setText("");
        temp11.put("name", name1);
        temp11.put("address", address1);
        temp11.put("location", location1);

        temp11.put("image", imgUri);
        targetImage.setImageBitmap(null);
        list12.add(0, temp11);
        adapter.notifyDataSetChanged();
    }

你读过这个文档吗？

特别是您需要检查如何管理内存。例如，在加载位图之前，您应该尝试验证需要使用哪些选项来缩小其大小。

这个答案可能会帮助您在尝试加载图像之前重新缩放图像所需的代码。

来自相机的大图像？尝试减小该图像的大小（降低相机设置中的分辨率）。

看起来您超出了应用程序可用的内存：

从您发布的日志中：

java.lang.OutOfMemoryError: bitmap size exceeds VM budget

但除此之外，您可能正在泄漏一些内存。您应该丢弃（回收）那些位图等。

@DigCamara 在他/她的回答中发布了一些出色的链接！真的，必须阅读您的情况。
