Question

我有一个从AutoCompleteTextView延伸的customAdapter，我有一个问题需要显示建议，我认为这是＆＃34; performFiltering＆＃34;但我不太清楚。

这是我的代码适配器：

我做错了什么？

import android.content.Context;
import android.graphics.Rect;
import android.util.AttributeSet;
import android.util.Log;
import android.view.KeyEvent;
import android.view.View;
import android.view.inputmethod.InputMethodManager;
import android.widget.AutoCompleteTextView;

public class InstantAutoComplete extends AutoCompleteTextView  {
    Context context;
    public InstantAutoComplete(Context context) {
        super(context);
        context = context;
    }

    public InstantAutoComplete(Context arg0, AttributeSet arg1) {
        super(arg0, arg1);
    }

    public InstantAutoComplete(Context arg0, AttributeSet arg1, int arg2) {
        super(arg0, arg1, arg2);
    }

    @Override
    public boolean enoughToFilter() {
        return true;
    }

    private boolean mIsKeyboardVisible;

    @Override
    protected void onFocusChanged(boolean focused, int direction,Rect previouslyFocusedRect) {

        super.onFocusChanged(focused, direction, previouslyFocusedRect);
        if (getWindowVisibility() == View.GONE) {
            Log.d("InstantAutoComplete", "Window not visible, will not show drop down");
            return;
        }
        if (focused) {
            /*try {*/
                performFiltering(getText(), 0);
            /*}catch (Exception e){
                Toast.makeText(context,"Click",Toast.LENGTH_SHORT).show();
            }*/
        }
        mIsKeyboardVisible = focused;
    }



    /*@Override
    public View getRootView() {
        return super.getRootView();
    }*/

    /*@Override
    protected void performFiltering(final CharSequence text, final int keyCode) {
        String filterText = "";
        super.performFiltering(filterText, keyCode);
    }*/

如果我使用＆＃34; AutoCompleteTextView＆＃34;工作正常，但如果使用＆＃34;自定义不起作用＆＃34;

解决方案：

使用默认的ArrayAdapter。我的自定义适配器出错了。

AutocompleteTextView（建议不正确）
