一种布局将另一种布局推离屏幕

Question

Currently i'm working one a small android project. I ran on a problem with layouts because I must create a user interface in Java. I have 2 layouts first is the LinearLayout with horizontal orientation and the other is a TableLayout. I set the width MATCH PARENT and height WRAP CONTENT for both of them but the first one pushes the other one off the screen and I want the first layout to push the other one under him.

The code looks like this:

    LinearLayout mainLayout = new LinearLayout(this);

    LinearLayout hLayout = new LinearLayout(this);
    hLayout.setOrientation(LinearLayout.HORIZONTAL);

    LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT,
    LayoutParams.WRAP_CONTENT); 
    hLayout.setLayoutParams(params);

    mainLayout.addView(hLayout);

    TableLayout table = new TableLayout(this);

    params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);

    table.setLayoutParams(params);

    mainLayout.addView(table);
    setContentView(mainLayout);

Answer 1

You don't seem to add hLayout to anything so it isn't being pushed off the screen but never added to the content view. Try something like

mainLayout.addView(table);
mainLayout.addView(hLayout);
setContentView(mainLayout);

Also, since the width is match_parent and LinearLayout has a default orientation of horizontal, you will either need to change the orientation of the mainLayout to vertical or change the width to wrap_content .

And is there a reason you are doing it programmatically? Creating layout s in xml is typically much easier.
