Please see my code below. I am unable to make SetGravity work.
How come?
Layout Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:padding="25dp"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:longClickable="true"
android:orientation="vertical" >
<EditText
android:id="@+id/etCommands"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Type a command"
android:password="true" />
<LinearLayout
android:weightSum="100"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:layout_weight="20"
android:id="@+id/btnResults"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Results" />
<ToggleButton
android:paddingBottom="10dp"
android:layout_weight="80"
android:id="@+id/passTog"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="ToggleButton" android:checked="true"/>
</LinearLayout>
<TextView
android:id="@+id/tvResults"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="invalid" />
</LinearLayout>
java code:
public class TextPlay extends Activity {
private static final String TAG = "MyApp";
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.text);
Button chkCmd = (Button) findViewById(R.id.btnResults);
final ToggleButton passTog = (ToggleButton) findViewById(R.id.passTog);
final EditText input = (EditText) findViewById(R.id.etCommands);
final TextView display = (TextView) findViewById(R.id.tvResults);
passTog.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (passTog.isChecked()) {
input.setInputType(InputType.TYPE_CLASS_TEXT
| InputType.TYPE_TEXT_VARIATION_PASSWORD);
} else {
input.setInputType(InputType.TYPE_CLASS_TEXT);
}
}
});
chkCmd.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
String check = input.getText().toString();
Log.i(TAG, "Check Value is: " + check);
if (check.contentEquals("left")) {
Log.i(TAG, "I am under left ");
display.setGravity(Gravity.LEFT); //WHYW ILL YOU NOT WORK SETGRAVITY?????????????
} else if (check.contentEquals("center")) {
display.setGravity(Gravity.CENTER);
} else if (check.contentEquals("right")) {
display.setGravity(Gravity.RIGHT);
}
else if (check.contentEquals("blue")) {
display.setGravity(Gravity.RIGHT);
}
}
});
}
}
I just tested and it works.. You might be doing a few things wrong;
First of all, when you type “left” into the text field, are you making sure that you didn’t type “Left” (most keyboards capitalize the first letter)
If you are sure about the above, do you see the log that says “I am under left ” (Not the “Check is”)? If not, then it’s not getting there somehow..
If you are indeed seeing it, you might want to clean/build your project (in Eclipse Project-> Clean -it does cleaning and re-building)
If that doesn’t work neither, you might want to change your target build (change it to API level 10 or so) You don’t really need to worry about the target build if you are just using this as an exercise to learn.
