对于我的活动，我们的任务是完全以编程方式创建视图（不允许使用XML）。

我创建了想要布局在XML中显示的外观。

但是我无法像我在XML文件中所做的那样，获取我的contentEditText和重力来正确设置它们。

这就是我的看法。

public class NoteGridLayout extends GridLayout {

  public NoteGridLayout(final Context context,EditText titleEditText,Spinner spinner,EditText contentEditText,Button backButton) {
    super(context);

    setColumnCount(2);

    GridLayout.Spec colSpec,rowSpec;
    colSpec = GridLayout.spec(0,1,1);
    rowSpec = GridLayout.spec(0,0);
    GridLayout.LayoutParams titleParams = new GridLayout.LayoutParams(rowSpec,colSpec);

    colSpec = GridLayout.spec(1,0);
    GridLayout.LayoutParams spinnerParams = new GridLayout.LayoutParams(rowSpec,colSpec);

    colSpec = GridLayout.spec(0,2,1);
    rowSpec = GridLayout.spec(1,1);
    GridLayout.LayoutParams contentParams = new GridLayout.LayoutParams(rowSpec,1);
    rowSpec = GridLayout.spec(2,0);
    GridLayout.LayoutParams buttonParams = new GridLayout.LayoutParams(rowSpec,colSpec);

    titleParams.width = 0;
    titleParams.height = LayoutParams.WRAP_CONTENT;
    spinnerParams.width = 0;
    spinnerParams.height = LayoutParams.WRAP_CONTENT;
    contentParams.width = 0;
    contentParams.height = 0;
    buttonParams.width = LayoutParams.MATCH_PARENT;
    buttonParams.height = LayoutParams.WRAP_CONTENT;
    contentParams.setGravity(Gravity.TOP);

    titleEditText.setLayoutParams(titleParams);
    spinner.setLayoutParams(spinnerParams);
    contentEditText.setLayoutParams(contentParams);
    backButton.setLayoutParams(buttonParams);


    addView(titleEditText);
    addView(spinner);
    addView(contentEditText);
    addView(backButton);
  }
}

我遇到的两个主要问题是： 1. titleEditText似乎没有覆盖整个列，而微调器占据了整个两列。 2.无法设置contentEditText重力，将文本置于框的顶部。

该如何解决这两个问题？
