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，我创建了两个文本视图，并以编程方式将它们添加到相对布局中。 我希望将它们并排排列。
代码运行正常，但没有将新的TextView放在上一个TextView的右边，而是将新的TextView定位在边距（0,0,0,0），即屏幕的右上角：
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);
请尝试以下方法：
- 将textView [0]的id设置为1而不是0（id需要为正整数）
- 添加到textView [1]的relativeLayoutParams为RelativeLayout.ALIGN_TOP的规则
以下对我有用：
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);
只是一个猜测：你可以尝试使用不同于0的ID吗？
