How to set EditText box height and width programma

问题:

I want to manage the height and width of an EditText box programmatically in Android. I tried edittext.setWidth(32); and edittext.setEms(50);, but both are not working. See my below code, as I am using it to create dynamic EditTexts in Android.

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;
}

回答1:

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.

回答2:

edittext.getLayoutParams().width=32;

回答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)));

回答4:

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

works for me. for example

    lparams.width = 32;

回答5:

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

Try the following code:-

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

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