Android TextView以编程方式跨越全宽

Question

我已经以编程方式在LinearLayout中创建了一个TextView:

LinearLayout filmTitleContainer = new LinearLayout(ctx);
TextView filmName = new TextView(ctx);
filmName.setBackgroundColor(Color.rgb(Color.YELLOW));
filmName.setText(this.screeningTime+" "+this.name);

文本视图缩小:

如何将文本设置为占据屏幕的整个宽度？当我使用XML布局文件时,我会设置android:layout_width="match_parent".什么是等效的Java代码？

使用LayoutParams两种视图及其容器:

LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT, 1f);
filmTitleContainer.setLayoutParams(params);
filmName.setLayoutParams(params);
