H TextViews里面有多个LinearLayout.现在我想在java中删除这个文本视图.视图是动态生成的.我怎样才能清空这里面的所有内容LinearLayout？

<LinearLayout android:layout_width="match_parent"
        android:layout_height="wrap_content" android:orientation="vertical" android:id="@+id/myid">

    <TextView .../>
    <TextView .../>
    <TextView .../>

</LinearLayout>

在sdcard中打开文件时,我的代码正常工作.但是,如果我打开带有空格的文件名,则会出现错误(例如:路径 - "/ sdcard/download/hello hi.jpg").

我试过string.replace("","%20"); 它不起作用

try {
    File file = new File(paths);
    if (file.exists()) {
        Uri path = Uri.fromFile(file);
        Intent intent = new Intent(Intent.ACTION_VIEW);
        String mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension(MimeTypeMap.getFileExtensionFromUrl(paths));

        if (!mimeType.equals("")) {
            intent.setDataAndType(path, mimeType);
            intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            startActivity(intent);
        } else {
            Toast.makeText(this, "Unsupported Format to Open", Toast.LENGTH_SHORT).show();
        }
    }
} catch (ActivityNotFoundException e) {
    Toast.makeText(this, "No Application Available to View this File", Toast.LENGTH_SHORT).show();
} catch(Exception e) {
    Toast.makeText(this, "Error Occurred", Toast.LENGTH_SHORT).show();
}

请帮忙
