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

在下面的代码中，我创建了两个 TextView ，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。

代码运行良好，但没有将新的 TextView 放在前一个 TextView 的右侧，而是将新的 TextView 放置在边距( 0,0,0,0) 即屏幕右上角:

    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);

Best Answer-推荐答案

尝试以下方法:

1. 将textView[0]的id设置为1而不是0(id需要为正整数)
2. 在 textView[1] 的 relativeLayoutParams 中添加 RelativeLayout.ALIGN_TOP 的规则

以下内容对我有用:

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);
