以编程方式创建具有固定像素宽度和高度的 TextView

Create TextView programatically with fixed pixel width and height

我试过下面的代码

dTextView = new TextView(getContext());
dTextView.setText(item.getText());
dTextView.setTextSize(8);
dTextView.setTextColor(Color.BLACK);
dTextView.setLayoutParams(new RelativeLayout.LayoutParams((int) measureWidth, (int) measureHeight));
setMargin(dTextView, item);
rootView.addView(dTextView);

不过,这不是我想要的确切尺寸。这些事情对于 CheckBox 视图也是一样的。我需要用精确的精确位置和大小来绘制这个视图。

为什么要这样做。

您可以创建一个文本视图组件,并借助 ListView、Recyclerview 等以编程方式将其添加到您的 UI

试试这个方法:

dTextView = new TextView(getContext());
dTextView.setText(item.getText());
dTextView.setTextSize(8);
dTextView.setTextColor(Color.BLACK);
RelativeLayout.LayoutParams params=new RelativeLayout.LayoutParams((int) measureWidth, (int)measureHeight));
setMargin(dTextView, item);
rootView.addView(dTextView, params);

最后,我创建了具有精确宽度和高度的所有视图(Checkbox、EditText 和 TextView)。 EditText 和 TextView 是一个简单的解决方案:

       dEditText = new EditText(getContext());
        dEditText.setPadding(10,5,10,5);
        dEditText.setTextSize(6);
        dEditText.setTextColor(Color.WHITE);
        dEditText.setBackgroundColor(Color.GRAY);
        RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
                (int) measureWidth, (int) measureHeight);
        dEditText.setLayoutParams(params);
        rootView.addView(dEditText);

        setMargin(dEditText, item,params);


// set margin of every created view
private void setMargin(View view, TagsItem item,RelativeLayout.LayoutParams layoutParams) {



    layoutParams.setMargins(item.getCurrentXPos(), item.getCurrentYPos(), 0, 0);

    // Apply the updated layout parameters to TextView
    view.setLayoutParams(layoutParams);
}

但是当我尝试使用此过程创建具有精确宽度和高度的 CheckBox 时,它没有创建具有精确宽度和高度的视图。我需要按照下面的代码[需要设置背景并为 setButtonDrawable 设置 null ]

 int states[][] = {{android.R.attr.state_checked}, {}};
        int colors[] = {Color.BLACK, Color.BLACK};

        dCheckBox = new CheckBox(getContext());
        CompoundButtonCompat.setButtonTintList(dCheckBox, new ColorStateList(states, colors));
        dCheckBox.setChecked(item.isCheckState());
        //dCheckBox.setText("");
        dCheckBox.setBackgroundResource(R.drawable.check_box_selector);
        dCheckBox.setButtonDrawable(null);



        RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
                (int) measureWidth, (int) measureHeight);
        dCheckBox.setLayoutParams(params);
       // checkBoxLayout.addView(dCheckBox);
        rootView.addView(dCheckBox);

        setMargin(dCheckBox, item,params);
