java - Android - 如何在代码中使 TextView fill_parent

Question

我试图让我的 TextView layout_width 填充父抛出代码。 这是我的代码:

 TextView WatchMovieTitle;

 private void PrintTheMovieAndYear() {
    if (CountWords() > 23) {
// this is what im doing wrong
 //             WatchMovieTitle.setLayoutParams
 //    (new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));

        WatchMovieTitle.setText(movieList.get("movieName") + " " + "("
                + movieList.get("movieYear") + ")");
        WatchMovieYear.setVisibility(View.GONE);
    } else {
        WatchMovieYear
                .setText(" " + "(" + movieList.get("movieYear") + ")");

    }
}

谢谢!

您可以使用

LayoutParams lp=new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);

或

LayoutParams lp=new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);

基于 TextView 的父布局。
