Question

我正在尝试使用自定义数据集来使用SearchWidget操作栏功能。问题是当我在搜索栏中输入任何字符时，建议ui为空。从日志中我看到使用了ContentProvider。但是，我不会在“可搜索活动”中看到任何日志。

@Override
public Cursor query(Uri uri, String[] projection, String selection,
                    String[] selectionArgs, String sortOrder) {
    // TODO: Implement this to handle query requests from clients.
    String query = uri.getLastPathSegment().toLowerCase();
    Log.d("app", "AAAAAAAAAAAAA "+query);

    String[] columnNames = {"_id", "Column1"};
    MatrixCursor matrixCursor = new MatrixCursor(columnNames);
    matrixCursor.addRow(new String[]{"1a", "r1v1"});
    matrixCursor.addRow(new String[]{"2a", "r2v1"});

    return matrixCursor;
    //adapter.swapCursor(matrixCursor);
    //throw new UnsupportedOperationException("Not yet implemented");
}

我的SearchableActivity有以下内容：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_searchable);
    Log.d("app", "NNNNNNNNNNNNNN");
    // Get the intent, verify the action and get the query
    Intent intent = getIntent();
    if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
        String query = intent.getStringExtra(SearchManager.QUERY);
    } else if (Intent.ACTION_VIEW.equals(intent.getAction())) {
        // Handle a suggestions click (because the suggestions all use ACTION_VIEW)
        Uri data = intent.getData();
    }
}

我想我错过了一些非常简单的步骤来连接一些点并显示结果。有人可以帮忙吗？

使用MatrixCursor时，SearchView显示为空
