在我的项目minSdkVersion = 10中,在库中它是11.

我明白了:

BUILD_FAILED - Manifest merger failed : uses-sdk:minSdkVersion 10 cannot be smaller than version 11 declared in library.

如何忽略库的minSdkVersion？

我正在使用自定义ArrayAdapter在AutocompleteTextView上设置适配器(AddressAdapter extends ArrayAdapter).

public class AutoCompleteAdapter extends ArrayAdapter<String> implements Filterable {
private ArrayList<String> mData;
ArrayList<String> listTempPrefix = new ArrayList<String>();
ArrayList<String> listTemp = new ArrayList<String>();
String valueText;
String[] words;
String ulcase;

public AutoCompleteAdapter(Context context, int textViewResourceId, ArrayList<String> bS) {
    super(context, textViewResourceId);
    mData = bS;//new ArrayList<String>();
}

@Override
public int getCount()
{
    synchronized (listTempPrefix)
    {
        return listTempPrefix.size();
    }
}

@Override
public String getItem(int index)  
{
    synchronized (listTempPrefix)
    {
        try {
            //Log.e("Error", listTempPrefix.get(index));
            return listTempPrefix.get(index);
        } catch(IndexOutOfBoundsException e) {
            Log.e("Error", "IndexOutOfBoundsException");
            return ""; …

如何检查AutoCompleteTextViewAndroid中的下拉状态(显示或隐藏)？

我从Gallery获取媒体文件.

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
            intent.setType("image/*,video/*,audio/*");
            startActivityForResult(Intent.createChooser(intent, "Select Media"), CameraUtils.REQUEST_GALLERY);

如何在onActivityResult()中确定媒体文件的类型？

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

    if (resultCode == RESULT_OK) {
        switch (requestCode) {
            case CameraUtils.REQUEST_GALLERY:
                Uri uri = data.getData();
                //what type of media file?
                break;
        }
    }
}
