問題描述

在下面的代碼中，我創(chuàng)建了兩個(gè)文本視圖，并以編程方式將它們添加到相對布局中.我想將它們并排對齊.

In the below code I have created two text views and added them programmatically to a relative layout. I want to align them side by side.

代碼運(yùn)行良好，但沒有將新的 TextView 放在前一個(gè) TextView 的右側(cè)，而是將新的 TextView 放置在邊距(0,0,0,0) 即屏幕右上角:

The code runs fine but is not placing the new TextView to the right of previous TextView instead the new TextView is positioned at margin (0,0,0,0) i.e. upper right corner of the screen:

    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);

推薦答案

試試以下:

1. 將textView[0]的id設(shè)置為1而不是0(id需要為正整數(shù))
2. 在 textView[1] 的 relativeLayoutParams 中添加 RelativeLayout.ALIGN_TOP 的規(guī)則

以下內(nèi)容對我有用:

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);
