Question

我使用listView创建了一个应用程序，listView包含使用数组的文本和图片。我有一个editText，用户可以使用搜索功能搜索列表。 listView加载正常但是当我点击editView搜索我的listView时，我得到outOfMemoryError。我不确定这是否与图像的大小有关。我知道之前已经问过这样的问题，但是他们都没有解决我的问题。

我的代码就像休耕一样

Insurance.java

public class Insurance extends AppCompatActivity {
    ListView list;
    ArrayAdapter<String> newadapter;
    EditText inputSearch;
    String[] itemname ={
            "AA",
            "Acorn",
            "Admiral",
            "AIG",
            "Allianz",
            "Auto Direct",
            "Aviva",
            "Carrot",


    };

    Integer[] imgid= {
            R.drawable.aa,
            R.drawable.acorn,

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        inputSearch = (EditText) findViewById(R.id.editText);
        list.setAdapter(newadapter);
        inputSearch.addTextChangedListener(new TextWatcher() {

            @Override

                Insurance.this.newadapter.getFilter().filter(cs);
            }

            @Override

        });
        list.setAdapter(adapter);
        list.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view,
                                    int position, long id) {
                // TODO Auto-generated method stub
                String Slecteditem = itemname[+position];
                Toast.makeText(getApplicationContext(), Slecteditem, Toast.LENGTH_SHORT).show();
                if (Slecteditem.toString() == "AA") {
                    Intent intent = new Intent(Intent.ACTION_DIAL);
                    intent.setData(Uri.parse("tel:028 9032 2232"));
                    startActivity(intent);
                }
                if (Slecteditem.toString() == "Carrot") {
                    Intent intent = new Intent(Intent.ACTION_DIAL);
                    intent.setData(Uri.parse("tel:028 9032 2265"));
                    startActivity(intent);
                }

我还在我的清单文件中包含了android:largeHeap="true"。

Answer 1

java.lang.OutOfMemoryError: Failed to allocate a 36000012 byte allocation with 16777216 free bytes and 21MB until OOM
    ...
    at android.support.v7.widget.AppCompatImageView.setImageResource(AppCompatImageView.java:72)
    at saveourcar.soc.CustomListAdapter.getView(CustomListAdapter.java:39)

您的CustomListAdapter在ImageView中放置了一个可绘制的资源。当对密度进行解码和缩放时，该可绘制资源是36000012字节。这相当于3000像素×3000像素的图像。

太大。找出这个资源是什么并修复它：

降低其分辨率
如果您将其放入res/drawable/，请将其移至更符合您打算使用的可绘制密度的目录，并consider having other versions of that drawable, at other resolutions, for other densities

我还包括android：largeHeap =＆＃34; true＆＃34;在我的清单文件中。

请撤消。
