Android – How to get the default text color for android TextView

androidcolorstextviewthemesview

I cannot get the default gray text color for TextView (and maybe other views) in Android 23.

I tried to get it with this code :

TextView textview= (TextView) mActivity.findViewById(R.id.my_textview);

int colorFirstTry = title.getCurrentTextColor(); // black
int colorSecondTry = title.getTextColors().getDefaultColor(); // black
int colorthirdTry = ContextCompat.getColor(mActivity, android.R.color.primary_text_light); // black

My theme is the default theme used in an blank activity project (AppTheme from Theme.AppCompat.Light.DarkActionBar parent). Colors are blue, darker blue and purple for respectively colorPrimary, colorPrimaryDark and colorAccent.

When i navigate through all Theme.AppCompat.Light.DarkActionBar parents, i find a similar gray value :

<style name="Base.V7.Theme.AppCompat.Light" parent="Platform.AppCompat.Light">   
    ...
    <item name="colorPrimaryDark">@color/primary_dark_material_light</item>

But this value shoud be overrided by my app theme value.

As said by Alex here, you can get it by:

android:textColor="@android:color/tab_indicator_text"

#808080

It worked great for me!

Android – How to center text horizontally and vertically in a TextView

I'm assuming you're using XML layout.

<TextView  
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:gravity="center"
    android:text="@string/**yourtextstring**"
/>

You can also use gravity center_vertical or center_horizontal according to your need.

and as @stealthcopter commented in java: .setGravity(Gravity.CENTER);

Android – How to get screen dimensions as pixels in Android

If you want the display dimensions in pixels you can use getSize:

Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;

If you're not in an Activity you can get the default Display via WINDOW_SERVICE:

WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
Display display = wm.getDefaultDisplay();

If you are in a fragment and want to acomplish this just use Activity.WindowManager (in Xamarin.Android) or getActivity().getWindowManager() (in java).

Before getSize was introduced (in API level 13), you could use the getWidth and getHeight methods that are now deprecated:

Display display = getWindowManager().getDefaultDisplay(); 
int width = display.getWidth();  // deprecated
int height = display.getHeight();  // deprecated

For the use case, you're describing, however, a margin/padding in the layout seems more appropriate.

Another way is: DisplayMetrics

A structure describing general information about a display, such as its size, density, and font scaling. To access the DisplayMetrics members, initialize an object like this:

DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);

We can use widthPixels to get information for:

"The absolute width of the display in pixels."

Example:

Log.d("ApplicationTagName", "Display width in px is " + metrics.widthPixels);

API level 30 update

final WindowMetrics metrics = windowManager.getCurrentWindowMetrics();
 // Gets all excluding insets
 final WindowInsets windowInsets = metrics.getWindowInsets();
 Insets insets = windowInsets.getInsetsIgnoreVisibility(WindowInsets.Type.navigationBars()
         | WindowInsets.Type.displayCutout());

 int insetsWidth = insets.right + insets.left;
 int insetsHeight = insets.top + insets.bottom;

 // Legacy size that Display#getSize reports
 final Rect bounds = metrics.getBounds();
 final Size legacySize = new Size(bounds.width() - insetsWidth,
         bounds.height() - insetsHeight);
