I'm trying to make a Button that changes to another activity, and at the same time creates a new textView with text from user input. I figured out how to do it on only one activity(I got it from this: LINK ). However, I want to do the exact same thing, except I want the button to take me to another activity and creates a textView there.
The point of this is to have an overview over accounts. You go to a "create account page", create an account, and the account shows up on the overview.
This is what I have so far:
First class:
public class MainActivity extends AppCompatActivity {
private EditText mEditText;
private Button mButton;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mEditText = (EditText) findViewById(R.id.editText);
mButton = (Button) findViewById(R.id.button);
mButton.setOnClickListener(onClick());
TextView textView = new TextView(getApplicationContext());
textView.setText("New text");
}
private View.OnClickListener onClick() {
return new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent buttonIntent = new Intent(MainActivity.this,
SecondLayout.class);
MainActivity.this.startActivity(buttonIntent);
mLayout.addView(createNewTextView(mEditText.getText().toString()));
}
};
}
private TextView createNewTextView(String text) {
final LinearLayout.LayoutParams lparams = new
LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
final TextView textView = new TextView(this);
textView.setLayoutParams(lparams);
textView.setText("New text: " + text);
return textView;
}
}
Second class:
public class SecondLayout extends AppCompatActivity {
public static LinearLayout mLayout;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mLayout = (LinearLayout) findViewById(R.id.linearLayout);
final Button addAccountButton = (Button)
findViewById(R.id.secondButton);
addAccountButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent buttonIntent = new Intent(SecondLayout.this,
MainActivity.class);
SecondLayout.this.startActivity(buttonIntent);
}
});
}
}
XML of first activity:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/firstlayout">
<EditText
android:id="@+id/firstText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="button"
/>
</LinearLayout>
XML of second activity:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/firstlayout">
<EditText
android:id="@+id/firstText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="button"
/>
</LinearLayout>
I'm very new to android studio and java, so there's probably some obvious mistakes that I can't see.
