Question

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。一个按钮拍摄照片相机以及 SD卡中的其他内容，然后他们在图片视图中添加图片。现在，当我在自定义列表视图中传递该图片时，第一次添加图片但是第二次应用程序崩溃....如果有人知道答案然后plz发布它。提前谢谢!!

这是代码。这是按钮点击..

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);

在此之后..

@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();
    }

logcat的

Answer 1

您是否阅读过this documentation？

特别需要查看manage memory的方法。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，例如。

在尝试加载图片之前，

This answer可能会帮助您重新扩展图片所需的代码。

Answer 2

来自相机的相当大的图像？尝试减小图像的大小（降低相机设置的分辨率）。

看起来你超出了你的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，你可能会泄漏一些记忆。你应该丢弃（回收）那些位图等。
