[英]How to set EditText box height and width programmatically in Android
I want to manage the height and width of an EditText
box programmatically in Android. 我想在Android中以编程方式管理
EditText
框的高度和宽度。 I tried edittext.setWidth(32);
我试过
edittext.setWidth(32);
and edittext.setEms(50);
和
edittext.setEms(50);
, but both are not working. ,但两者都不起作用。 See my below code, as I am using it to create dynamic
EditText
s in Android. 请参阅下面的代码,因为我正在使用它在Android中创建动态
EditText
。
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;
}
private EditText createEditText()
{
final LayoutParams lparams = new LayoutParams(50,30); // Width , height
final EditText edittext = new EditText(this);
edittext.setLayoutParams(lparams);
return edittext;
}
Try this. 试试这个。
edittext.getLayoutParams().width=32;
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)));
RelativeLayout.LayoutParams.width = 32;
RelativeLayout.LayoutParams.height = 50;
works for me. 适合我。 for example
例如
lparams.width = 32;
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) edittext.getLayoutParams();
params.width = mScreenWidth / 5;
params.height = mScreenWidth / 5;
edittext.setLayoutParams(params);
Try the following code:- 请尝试以下代码: -
Display display = getWindowManager().getDefaultDisplay();
int screenWidth = display.getWidth();
int screenHeight = display.getHeight();
profile_pic.getLayoutParams().height=(screenHeight/6);
profile_pic.getLayoutParams().width=(screenHeight/6);
