在自定義列表視圖中添加圖像時，Android應用崩潰

Question

我正在制作自定義列表視圖 ，其中我必須添加用戶從sd卡或相機拍攝的圖像。為此，我拍攝一個圖像視圖和兩個按鈕。一個按鈕從相機拍攝照片，另一個從sd卡拍攝照片，然后添加現在，當我在自定義列表視圖中傳遞該圖像uri時，將首次添加圖像，但第二次應用程序崩潰....如果有人知道答案，則請發布它。 提前致謝！！

這是代碼。 這是用於按鈕單擊。

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);

在這之后..

@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();
                }
            }

        }

然后我在列表視圖中添加圖像

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();
    }

Answer 1

您閱讀過此文檔嗎？

特別是，您需要檢查如何管理內存 。 例如，在加載位圖之前，您應該嘗試驗證需要使用哪些選項來縮小其尺寸。

此答案可能會幫助您提供在嘗試加載圖像之前需要重新縮放圖像的代碼。

Answer 2

相機的大圖像？ 嘗試減小該圖像的尺寸（減小相機設置中的分辨率）。

看起來您超出了應用程序可用的內存：

從您發布的日志中：

java.lang.OutOfMemoryError: bitmap size exceeds VM budget

但是除此之外，您可能正在泄漏一些內存。 您應該丟棄（回收）那些位圖等。
