我用listView制作了一个应用程序，listView包含使用数组的文本和图片。我还有一个 editText，用户可以使用搜索功能在列表中进行搜索。 listView 加载正常，但是当我单击 editView 搜索我的 listView 时，我收到 outOfMemoryError。我不确定这是否与图像的大小或其他因素有关。我知道以前曾有人问过类似的问题，但没有一个能解决我的问题。
我的代码是休闲的
保险.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,
R.drawable.admiral,
R.drawable.aig,
R.drawable.allianz,
R.drawable.autodirect,
R.drawable.aviva,
R.drawable.carrot,
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_insurance);
CustomListAdapter adapter=new CustomListAdapter(this, itemname, imgid);
list=(ListView)findViewById(R.id.list);
newadapter = new ArrayAdapter<String>(this, R.layout.mylist, R.id.item, itemname);
inputSearch = (EditText) findViewById(R.id.editText);
list.setAdapter(newadapter);
inputSearch.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
// When user changed the Text
Insurance.this.newadapter.getFilter().filter(cs);
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
}
});
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 list 文件中包含了 android:largeHeap="true"。

最佳答案
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正在将可绘制资源放入ImageView中。该可绘制资源在解码并缩放密度后为 36000012 字节。这相当于 3000 像素 x 3000 像素的图像。
这太大了。找出这个资源是什么并修复它:
降低分辨率
如果您将其放入
res/drawable/中，请将其移至更能指示您希望使用该可绘制对象的密度的目录，并且 consider having other versions of that drawable, at other resolutions, for other densities
I have also included android:largeHeap="true" in my Manifest file.
请撤消该操作。
关于java.lang.OutOfMemory错误: Failed to allocate a 36000012 byte allocation with 16777216 free bytes and 21MB until OOM，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/36652716/
