Android Application Development Tutorial - 29 - Set Gravity within Java

[ttttkk]

Wow, I can't believed I can ever watch 29 youtube tutorial in a row!

If you want to make the input not canse senitive, you can replace all of the 'contentEquals(String str)' methods with 'equalsIgnoreCase(String str)' methods.

Alternativly, you can put "check = check.toLowerCase();' right before the first if-statement. This will work since the string we compare 'check' to (left, right and center) is all lowercase.

The gravity issue: You should check the .xml in graphical layout if the blue box around that "invalid" text have enough room to move (to left, right).
I fixed puting a number in android:layout_width="250dp" instead of wrap_content or fill_parent
It´s only a matter of space.
You can put display.setText("left") inside of the "if (left)" statement to check if the code working properly, and the same for the right and center.

I am beginner too, but this code works for me:

(IMPORTANT! LayoutParams must be

LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.gravity = Gravity.LEFT;
tv.setLayoutParams(params);

Thanks for this! Worked!
I think Gravity needs to be above fill parent. Maybe someone can post the logic behind this so we can *learn* why, rather than blundering around.

Im not sure how to fix the simulator being slow but I have managed to get the keyboard working.
Open Android Device Manager - > Click your simulator -> Edit
Under Hardware; click New -> Select: 'Keyboard Support' -> Ok
Under the new Item listed in hardware, change the value of Keyboard support from 'no' to 'yes'

@justinrixx is your layout_width set to fill_parent?

[herp_derpingson]

@igunIGN Yes you can use switch case: block instead of if statements

[methooverload]

I would use check.toUpperCase() to upper case the String and whatever you are comparing have it in ALL upper case this is good programming techniques as all constants should be in all caps.

[MBserieHD]

instead of you should use
and you should use

[TamaraWirz]

Thanks for saying your name this time...I could never remember it.

[HeyMyAwesomePeople]

If you guys don't want it case sensitive, just use: check.equalsIgnoreCase()

[tjballe]

@justinrixx I have the same problem! Help is appreciated. Have done exactly like the tutorial but for some reason the setGravity doesnt change the gravity inside the textview :(

[mastermax]

@SkimpyDoughnut lol nvm xP
check that your findViewById are exactly same like in ur textplay.xml

[amzaionutcatalin]

We can use switch(check) instead if statement?

i have a "yellow error" that states, "Hardcoded string...should use @string resource" what does that mean? Since the error is not red, I am still able to test launch the app...except I don't know if that "yellow error" will be a future problem. please help!

[Baaataaataaa]

@justinrixx
so I did the next tutorial with this one and then everything worked perfectly including gravity with no crashing!!

Wow man the password toggle is not working really smooth. I'm debugging it on my phone though (Galaxy Nexus, ICS), that might be why... but it still seems very strange. I can type without problems with password chars ON, but when i turn them off i can only type certain characters. It's really weird.

[palmeirasdf]

Hello guys, my application gives error (unfortunately has stopped) when I click the button "Try Command." What can be??

[Varttino]

the String references to the EditText and the If/Else refer to the TextView, if this helps somebody
