How change background color of View Android sample.
MainActivity.java
main.xml
MainActivity.java
public class MainActivity extends Activity {
TextView hTextView;
TableRow hTableRow;
Button hButton, hButtonStop;
private Handler mHandler = new Handler();
private int nCounter = 0;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
hTextView = (TextView)findViewById(R.id.idTextView);
hButton = (Button)findViewById(R.id.idButton);
hButton.setOnClickListener(mButtonStartListener);
hTableRow = (TableRow)findViewById(R.id.idTableRow1);
} // end onCreate
View.OnClickListener mButtonStartListener = new OnClickListener() {
public void onClick(View v) {
hTableRow.setBackgroundColor(Color.YELLOW);
}
};
}
main.xml
<?xml version="1.0" encoding="utf-8"?>

build.gradle in module have higher priority then AndrodiManifest.xml
Try this.
AndroidManifest.xml have code:
build.gradle have code:
Warning in AndroidManifest.xml:
Try this.
AndroidManifest.xml have code:
<uses-sdk
android:minSdkVersion="9"
android:targetSdkVersion="23" />
build.gradle have code:
defaultConfig {
applicationId "cz.okhelp.words"
minSdkVersion 9
targetSdkVersion 19
versionCode 107
versionName "1.0.7"
}
Warning in AndroidManifest.xml:
This targetSdkVersion value (23) is not used; it is always overridden by the value specified in the Gradle build script (19) less... (Ctrl+F1)
The value of (for example) minSdkVersion is only used if it is not specified in the build.gradle build scripts. When specified in the Gradle build scripts, the manifest value is ignored and can be misleading, so should be removed to avoid ambiguity.
Date difference in millisecond between two date, GregorianCalendar, Calendar, after(), befor(), getTimeInMillis().
public class HoriziontalScrollActivity extends Activity {
TextView txtV;
Context cntx;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
txtV = (TextView)findViewById(R.id.idLabel);
cntx = this;
StringBuilder strBuild = new StringBuilder();
Calendar firstDate = new GregorianCalendar(2011, Calendar.DECEMBER, 31);
Calendar secondDate = new GregorianCalendar(2012, Calendar.JANUARY, 1);
Boolean bDetermine = firstDate.after(secondDate); // false
strBuild.append("Is firsDate after secondDate? " + bDetermine + "
");
bDetermine = firstDate.before(secondDate); // true
strBuild.append("Is firsDate before secondDate? " + bDetermine + "
");
long differenceInMillisecond = 0L;
differenceInMillisecond = secondDate.getTimeInMillis()-firstDate.getTimeInMillis();
// second == 1000 millisecond
long second = differenceInMillisecond / 1000L;
strBuild.append("Difference between two dates is: " + second + "
");
txtV.setText(strBuild);
}
}
Switch statement with numbers and array of strings Java example.
Possible:
public class MainClass {
public static void main(String[] arg) {
String[] arrayOfString = { "One", "Two", "Three", "Four" };
int i = 2;
switch (i) {
case 1: {
System.out.println(arrayOfString[i]);
break;
}
case 2: {
System.out.println(arrayOfString[i]);
break;
}
case 3: {
System.out.println(arrayOfString[i]);
break;
}
default: {
System.out.println("Enter a valid value.");
}
} // END of switch
}
}
/*
* Three
*/
Possible:
case 1:
System.out.println(arrayOfString[i]);
break;
// i love this notation
case 1:{
System.out.println(arrayOfString[i]);
}break;
case 1:{
System.out.println(arrayOfString[i]);
break;
}
