i want privacy policy , disclaimer statement and a color picker as 1 time run activity when the app is installed . So how can i use persistent storage so that when we install and run the app for the first time privacy policy runs then clicking on button(next) goes to disclaimer activity then to color picker and finally to main activity. And when second time app is run it directly goes to main activity.
MAIN ACTIVITY:
public static final String PREFS_NAME = "MyPrefsFile"; // Name of prefs file; don't change this after it's saved something
//public static final String PREFS_NAME = "MyPrefsFile";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0); // Get preferences file (0 = no option flags set)
boolean firstRun = settings.getBoolean("firstRun", false); // Is it first run? If not specified, use "true"
if (firstRun == false) {
Log.w("activity", "first time");
setContentView(R.layout.activity_gasfurnancediagnostics);
SharedPreferences.Editor editor = settings.edit(); // Open the editor for our settings
editor.putBoolean("firstRun", false); // It is no longer the first run
editor.apply(); // Save all changed settings
return;
} else {
Log.w("activity", "second time");
checkColor();
setContentView(R.layout.activity_theme);
return;
}
// setContentView(R.layout.activity_main);
//*** CHECKING COLOR IF IT WAS SET PREVIOUSLY ***/
}
public void checkColor()
{
// INITIALIZING THE SHARED PREFRENECES
SharedPreferences pref = getApplicationContext().getSharedPreferences("Colors", 0);
// CHECK IF WE HAVE COLOR_SET VALIRABLE IF NOT DEFAULT WILL BE 0
int color_set = pref.getInt("color_set", 0);
if(color_set==0){
Intent e = new Intent(getApplicationContext(), ThemeActivity.class);
startActivity(e);
return;
}
if(color_set==1)
{ // IF IT IS ALREADY SET IN THE PREVIOUS THAN THIS CAN BE USED FOR REDIRECTING TO OTHER CONTROLLER AND THE BELOW FUNCTIONS CAN BE USED IN THAT CONTROLLER FOR COLOR MODIFICATIUON
String color = pref.getString("color", null); // COLOR CODE
ActionBar mActionBar = getActionBar(); // GETTING ACTIONBAR
//final Button testbutn = (Button) findViewById(R.id.testbtn); // GETTING BUTTON
if (color.equals("red")) {
mActionBar.setBackgroundDrawable(new ColorDrawable(0xFFBA1E1E)); // CHANGES ACTION BAR COLOR
// testbutn.setBackgroundColor(0xFFFF6666);
// CHANGES BUTTON COLOR
} else if (color.equals("blue")) {
mActionBar.setBackgroundDrawable(new ColorDrawable(0xFF21a4dd)); // CHANGES ACTION BAR COLOR
// testbutn.setBackgroundColor(0xFFFF4B7E); // CHANGES BUTTON COLOR
}
else if (color.equals("yellow")) {
mActionBar.setBackgroundDrawable(new ColorDrawable(0xFFF6D72B)); // CHANGES ACTION BAR COLOR
// testbutn.setBackgroundColor(0xFFFF4B7E); // CHANGES BUTTON COLOR
}
mActionBar.setDisplayShowTitleEnabled(false); // THESE TWO STEPS ARE REQUIRED AFTER CHANGING THE ACTION BAR COLOR
mActionBar.setDisplayShowTitleEnabled(true); // THESE TWO STEPS ARE REQUIRED AFTER CHANGING THE ACTION BAR COLOR
}
