How can I remove all default padding from EditText?

阅读更多关于 How can I remove all default padding from EditText?

I am using an EditText and it always adds a bit of padding in my text to both left and right.

How can I strip all padding from the EditText that is being added by default? <EditText android:layout_width="match_parent" android:layout_height="wrap_content" android:minHeight="20dp" android:fontFamily="roboto-regular" android:layout_gravity="center_vertical" android:gravity="center_vertical" android:layout_marginLeft="-5dp" android

How could I move the EditText automatically just above the keyboard, when it has been pressed? At the end, it would be good if it would look like this: My Code: // LINEAR LAYOUT LinearLayout layout = new LinearLayout(getApplicationContext()); layout.setOrientation(LinearLayout.VERTICAL); setContentView(layout); // TEXTVIEW layout.addView(tv); // EDITTEXT et.setGravity(Gravity

阅读更多关于 Android: Edittext- get current line

问题 In an edittext is there a method for getting the current line of the cursor? If not I will write my own method, but just wanted to check. If I do write my own method would the best method be to go through every character in the edittext until selectionstart and count the number of \n's using a For loop, or is there a better way? Thanks! 回答1: Just to let people know: There is a better way to do this then Doug Paul has suggested by using the getLineForOffset(selection) : public int

阅读更多关于 Create a multiline EditText programmatically

I am trying to create a multiline EditText by code. This is what I use: EditText txt = new EditText(this); lp = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT, 1.0f); txt.setLayoutParams(lp); txt.setSingleLine(false); txt.setInputType(InputType.TYPE_TEXT_FLAG_MULTI_LINE); But it is still in one single line.
