如何以编程方式将Android TextView对齐到另一个TextView的右侧

Question

在下面的代码中，我创建了两个文本视图，并以编程方式将它们添加到相对布局中。我想将它们并排对齐。

该代码运行良好，但未将新代码放置在上一个代码TextView的右侧，TextView而是将新代码放置TextView在屏幕的右上角（0,0,0,0）处，即：

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    relativeLayout= (RelativeLayout) findViewById(R.id.relative_Layout);

    textView[0] = new TextView(this);//creates first textview
    textView[0].setId(0);
    textView[0].setText("1");
    textView[0].setBackgroundResource(R.drawable.shape);//parses an image from shape.xml

    relativeLayoutParams.addRule(RelativeLayout.CENTER_IN_PARENT);
    textView[0].setLayoutParams(relativeLayoutParams);

    relativeLayout.addView(textView[0]);//creates another textview

    textView[1] = new TextView(this);

    textView[1].setBackgroundResource(R.drawable.shape);

    RelativeLayout.LayoutParams relativeLayoutParams=
            new RelativeLayout.LayoutParams((RelativeLayout.LayoutParams.WRAP_CONTENT),(RelativeLayout.LayoutParams.WRAP_CONTENT));//create params for new textview

    relativeLayoutParams.addRule(RelativeLayout.RIGHT_OF, textView[0].getId());//to align the textview side by side
    textView[1].setText("2");

    relativeLayout.addView(textView[1], relativeLayoutParams);

Answer 1

请尝试以下操作：

1. 将textView [0]的ID设置为1而不是0（ID必须为正整数）
2. 将规则RelativeLayout.ALIGN_TOP添加到textView [1]的relativeLayoutParams中

以下为我工作：

RelativeLayout relativeLayout = (RelativeLayout) findViewById(R.id.test);
RelativeLayout.LayoutParams relativeLayoutParams;       
TextView[] textView = new TextView[2];

// 1st TextView
textView[0] = new TextView(this);

relativeLayoutParams = new RelativeLayout.LayoutParams(
        RelativeLayout.LayoutParams.WRAP_CONTENT,
        RelativeLayout.LayoutParams.WRAP_CONTENT);

textView[0].setId(1); // changed id from 0 to 1
textView[0].setText("1");

relativeLayoutParams.addRule(RelativeLayout.CENTER_IN_PARENT);

relativeLayout.addView(textView[0], relativeLayoutParams);

// 2nd TextView
textView[1] = new TextView(this);

relativeLayoutParams = new RelativeLayout.LayoutParams(
        RelativeLayout.LayoutParams.WRAP_CONTENT,
        RelativeLayout.LayoutParams.WRAP_CONTENT);

textView[1].setText("2");

relativeLayoutParams.addRule(RelativeLayout.RIGHT_OF,
        textView[0].getId());
relativeLayoutParams.addRule(RelativeLayout.ALIGN_TOP,
        textView[0].getId()); // added top alignment rule

relativeLayout.addView(textView[1], relativeLayoutParams);
