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

試試這個。

這使我NullPointerExceptions的... :-( – JerabekJakub 2014-08-23 08:53:04

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)));

試試下面的代碼： -

Display display = getWindowManager().getDefaultDisplay(); 
    int screenWidth = display.getWidth(); 
    int screenHeight = display.getHeight(); 

profile_pic.getLayoutParams().height=(screenHeight/6); 
    profile_pic.getLayoutParams().width=(screenHeight/6);

RelativeLayout.LayoutParams.width = 32; 
RelativeLayout.LayoutParams.height = 50;

爲我工作。例如

lparams.width = 32;

LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) edittext.getLayoutParams(); 
      params.width = mScreenWidth/5; 
      params.height = mScreenWidth/5; 
      edittext.setLayoutParams(params);
