【问题描述】：

下面是我的布局。

我想要的是 2 个绿色箭头在左上角的正方形中垂直居中。此外，双数字符号（“##”）需要在左上角的正方形中垂直和水平居中。

然后，另一组双数字符号需要在右上角的正方形中垂直和水平居中。

下面是代码。

public class Puzzle extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {        
        super.onCreate(savedInstanceState);

        dividers();
        topLeft();
        topRight();

        setContentView(relativelayout);
    }

    public void topLeft() {

        RelativeLayout.LayoutParams params0 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
        params0.addRule(RelativeLayout.ABOVE, view0.getId());
        params0.addRule(RelativeLayout.LEFT_OF, view1.getId());
        relativelayout.addView(topLeftRL, params0);

        RelativeLayout.LayoutParams params1 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        params1.addRule(RelativeLayout.ALIGN_PARENT_TOP);
        params1.addRule(RelativeLayout.CENTER_HORIZONTAL);
        topLeftRL.addView(puzzle, params1);

        RelativeLayout.LayoutParams params2 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        params2.addRule(RelativeLayout.CENTER_VERTICAL);
        params2.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
        topLeftRL.addView(left, params2);

        RelativeLayout.LayoutParams params3 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        params3.addRule(RelativeLayout.CENTER_VERTICAL);
        params3.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
        topLeftRL.addView(right, params3);

        RelativeLayout.LayoutParams params4 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        params4.addRule(RelativeLayout.CENTER_IN_PARENT);
        topLeftRL.addView(levelCounter, params4);

        left.setImageResource(R.drawable.left_arrow);
        right.setImageResource(R.drawable.right_arrow);
        puzzle.setText(c.getResources().getString(R.string.puzzlePuzzleTV));
        levelCounter.setText("###");
    }

    public void topRight() {

        RelativeLayout.LayoutParams params0 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
        params0.addRule(RelativeLayout.ABOVE, view0.getId());
        params0.addRule(RelativeLayout.RIGHT_OF, view1.getId());
        relativelayout.addView(topRightRL, params0);

        RelativeLayout.LayoutParams params1 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        params1.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
        params1.addRule(RelativeLayout.CENTER_HORIZONTAL);
        topRightRL.addView(record, params1);

        RelativeLayout.LayoutParams params2 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        params2.addRule(RelativeLayout.ALIGN_PARENT_TOP);
        params2.addRule(RelativeLayout.CENTER_HORIZONTAL);
        topRightRL.addView(moves, params2);

        RelativeLayout.LayoutParams params3 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        params3.addRule(RelativeLayout.CENTER_IN_PARENT);
        topRightRL.addView(movesCounter, params3);

        movesCounter.setText("##");
        record.setText(c.getResources().getString(R.string.puzzleRecordTV) + " " + "##");
        moves.setText(c.getResources().getString(R.string.puzzleMovesTV));
    }

    public void dividers() {

        // vertical line (top of screen)
        RelativeLayout.LayoutParams params1 = new RelativeLayout.LayoutParams(5, height / 6);
        params1.addRule(RelativeLayout.CENTER_HORIZONTAL);
        params1.setMargins(0, 10, 0, 10);  // left, top, right, bottom
        relativelayout.addView(view1, params1);

        // horizontal line (top of screen)
        RelativeLayout.LayoutParams params0 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, 5);
        params0.addRule(RelativeLayout.BELOW, view1.getId());
        params0.setMargins(10, 0, 10, 0);  // left, top, right, bottom
        relativelayout.addView(view0, params0);

        // horizontal line (button of screen)
        RelativeLayout.LayoutParams params3 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, 5);
        params3.addRule(RelativeLayout.ABOVE, linearlayout.getId());
        relativelayout.addView(view3, params3);
    }
}

所以看起来当我将多个addRule() 添加到一个参数时，它不会同时读取它们。我认为问题出在topLeft() 方法的这一行：params0.addRule(RelativeLayout.ABOVE, view0.getId());。我试过用那个参数中的另一个 addRule 切换这条线，结果是一样的。这是为什么呢？

【解决方案1】：

您正在使用需要锚点的参数。你需要使用“addRule(int verb, int anchor)”

很喜欢

params1.addRule(RelativeLayout.ALIGN_PARENT_TOP,1);

【讨论】：

一些addRule()s 不需要锚。您指出的那个工作正常并使用该参数正确显示 TextView 。我认为问题出在params0.addRule(RelativeLayout.ABOVE, view0.getId()); 这一行，它在topLeft() 方法中。
顺便说一下，我编辑了开头帖子中的代码，以便于阅读。

【解决方案2】：

我找到了自己问题的答案。错误出现在我的onCreate() 方法的一部分中，我没有包含在我的开篇帖子中！这是问题代码：

view0.setId(0);

显然id不能设置为0。无论如何，我将id号更改为正数，一切正常。
