如何在Android中以编程方式设置EditText框的高度和宽度

Question

我想EditText在Android中以编程方式管理框的高度和宽度.我试过edittext.setWidth(32);和edittext.setEms(50);,但两者都没有工作.请参阅下面的代码,因为我正在使用它EditText在Android中创建动态s.

private EditText createEditText()
{
    final LayoutParams lparams = new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT);
    final EditText edittext = new EditText(this);
    edittext.setLayoutParams(lparams);
    edittext.setWidth(32);
    edittext.setEms(50);
    return edittext;
}

Answer 1

private EditText createEditText()
{
    final LayoutParams lparams = new LayoutParams(50,30); // Width , height
    final EditText edittext = new EditText(this);
    edittext.setLayoutParams(lparams);
    return edittext;
}

试试这个.

Answer 2

edittext.getLayoutParams().width=32;

Answer 3

DisplayMetrics metrics = new DisplayMetrics();
WindowManager wm = (WindowManager) this.getSystemService(Context.WINDOW_SERVICE);
wm.getDefaultDisplay().getMetrics(metrics);
final float height = metrics.heightPixels;

EditText edittext = new EditText(this);

edittext.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT,(int) (height/2)));
