Every time i click onClickCreateButton i get this in return: android.content.res.Resources$NotFoundException: String resource ID #0x1
Main Activity class is as follows:
public class MainActivity extends AppCompatActivity {
EditText mInput;
RelativeLayout.LayoutParams layoutParams;
LinearLayout linearLayout2;
LinearLayout linearLayout3;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mInput = findViewById(R.id.EditText);
linearLayout2 = findViewById(R.id.LinearLayout2);
layoutParams = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
linearLayout3 = new LinearLayout(this);
linearLayout3.setLayoutParams(layoutParams);
linearLayout3.setOrientation(LinearLayout.HORIZONTAL);
linearLayout2.addView(linearLayout3);
}
public void onClickCreateButton(View v) {
LinearLayout temp;
try {
Toast.makeText(getApplicationContext(), linearLayout2.getChildCount(), Toast.LENGTH_SHORT).show();
if (linearLayout2.getChildCount() <= 8) {
temp = (LinearLayout) linearLayout2.getChildAt(linearLayout2.getChildCount());
Toast.makeText(getApplicationContext(), temp.getChildCount(), Toast.LENGTH_SHORT).show();
if (temp.getChildCount() <= 3) {
Button button = new Button(this);
button.setText(mInput.getText().toString());
button.setLayoutParams(layoutParams);
linearLayout3.addView(button);
} else {
linearLayout3 = new LinearLayout(this);
linearLayout3.setLayoutParams(layoutParams);
linearLayout3.setOrientation(LinearLayout.HORIZONTAL);
linearLayout2.addView(linearLayout3);
}
}
} catch (Exception ex)
{
Toast.makeText(getApplicationContext(), ex+"", Toast.LENGTH_SHORT).show();
}
}
activity_main:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<LinearLayout
android:id="@+id/LinearLayout2"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" />
</LinearLayout>
It would be of great help is someone could point out the mistake in my code. Thanks! Cheers!
Toast.makeText(getApplicationContext(), temp.getChildCount(), Toast.LENGTH_SHORT).show();
temp.getChildCount()
returns an int
and the Toast.makeText()
overload that takes an int
argument there expects it to be a resource id. Use the String
overload instead by converting the int
to a string, eg
Toast.makeText(getApplicationContext(), "" + temp.getChildCount(), Toast.LENGTH_SHORT).show();
Same issue with the other Toast
.
You're trying to show a number by calling the version of Toast.makeText
that takes a resource ID :
Toast.makeText(getApplicationContext(), temp.getChildCount(), Toast.LENGTH_SHORT).show();
You should convert it to a string:
Toast.makeText(getApplicationContext(), Integer.toString(temp.getChildCount()), Toast.LENGTH_SHORT).show();
