如何以編程方式將Android TextView對齊到另一個TextView的右側

Question

在下面的代碼中，我創建了兩個文本視圖，並以編程方式將它們添加到相對布局中。 我想將它們並排對齊。

該代碼運行良好，但是沒有將新的TextView放在先前的TextView的右側，而是將新的TextView定位在屏幕的右上角（0,0,0,0）的空白處：

    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

請嘗試以下操作：

1. 將textView [0]的ID設置為1而不是0（ID必須為正整數）
2. 向textView [1]的relativeLayoutParams中添加RelativeLayout.ALIGN_TOP的規則

以下為我工作：

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);

只是一個猜測：您可以嘗試使用不同於0的id嗎？
