BufferedReader , FileReader, StringBuilder , readLine, close Java example
Android example
Java example
Android example
String MYFILE = "my_file";
FileInputStream fis = openFileInput(MYFILE);
int c; String sText = "";
while((c=fis.read())!=-1)
{
sText += (char)c; // convert int to char
}
fis.close();
Java example
try {
BufferedReader in = new BufferedReader(new FileReader("myfile.txt"));
StringBuilder strBuilder = new StringBuilder();
String str;
while ((str = in.readLine()) != null) {
strBuilder.append(str);
}
in.close();
} catch (IOException e) {
e.toString();
}
// in strings.xml
<string name="myStringWithTags"><![CDATA[<b>some text..</b> other tags ...]]></string>
<string name="myStringWithPattern"><![CDATA[<b>%s</b> other tags ...]]></string>
// in Activity.class
String sHtmlText = this.getApplicationContext().getString(R.string.myStringTags);
sHtmlText = this.getApplicationContext().getString(R.string.myStringWithPattern,"replace %s with this text");
If you using Context as parameter of function try this solution:
public class MyActivity extends Activity {
// bla bla bla .......
//error
myFc( getapplicationcontext());
// OK
myFc(MyActivity.this);
onSaveInstanceState, onRestoreInstanceState , save preferences
int mCurrentPhotoIndex = 0;
@Override
protected void onSaveInstanceState(Bundle outState) {
outState.putInt("photo_index", mCurrentPhotoIndex);
super.onSaveInstanceState(outState);
}
@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
mCurrentPhotoIndex = savedInstanceState.getInt("photo_index");
super.onRestoreInstanceState(savedInstanceState);
}
// or save preferences for new start of Activity in onStop
//onCreate or onResume or onStart etc.
public void loadPreferences() {
SharedPreferences settings = getSharedPreferences(F.PREFERENCES_NAME, 0);
mCurrentPhotoIndex = settings.getInt("mCurrentPhotoIndex",mCurrentPhotoIndex);
// String_sOtazka = settings.getString("_sOtazka", _sOtazka);
}
// onStop
public void savePreferences() {
SharedPreferences settings = getSharedPreferences(PREFERENCES_NAME, 0);
SharedPreferences.Editor editor = settings.edit();
editor.putInt("mCurrentPhotoIndex", mCurrentPhotoIndex);
// String, boolean, float ...
// editor.putString("mButton1", mButton1.getText().toString());
editor.commit();
}
break statement in Java Android basic example
MainClass.java
MainClass.java
public class MainClass {
public static void main(String[] arg) {
String[] arrayOfString = {"nothing", "Hello", "people"
, "bye-bye", "hello", "world!", "end" };
for (int i = 0; i < arrayOfString.length; i++) {
System.out.println(arrayOfString[i]);
if(i > 2)
break; // end of loop
}
}
}
/*
nothing
Hello
people
bye-bye
*/
