使用EditText过滤支持SimpleCursorAdapter的ListView

    android:id="@+id/edit_text"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="请输入关键字" /><ListView
    android:id="@+id/list_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

EditText editText = findViewById(R.id.edit_text);
ListView listView = findViewById(R.id.list_view);

// 创建SimpleCursorAdapter适配器
SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, android.R.layout.simple_list_item_1, cursor, new String[]{"column_name"}, new int[]{android.R.id.text1}, 0);
listView.setAdapter(adapter);

// 添加EditText文本变化监听器
editText.addTextChangedListener(new TextWatcher() {
    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
    }

    @Override
    public void afterTextChanged(Editable s) {
        // 更新ListView数据
        Cursor newCursor = getFilteredCursor(s.toString());
        adapter.swapCursor(newCursor);
    }
});

private Cursor getFilteredCursor(String keyword) {
    // 根据关键字查询数据库，返回过滤后的Cursor
    return getContentResolver().query(YourContentProvider.CONTENT_URI, null, "column_name LIKE ?", new String[]{"%" + keyword + "%"}, null);
}
