POCreating dynamic buttons using two layouts in android
text
Body
copied!<p>I would like to create dynamic buttons in my main activity. The buttons are in a separate activity with an own layout file. I can show you my test project. I guess it could be better, but I am still a beginner in this field. ;-)</p> <p>This is my main activity. Nothing special:</p> <pre><code>package de.example.testprojekt; import android.os.Bundle; import android.app.Activity; import android.view.Menu; import android.view.MenuItem; import android.support.v4.app.NavUtils; public class MainActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_main, menu); return true; } } </code></pre> <p>I have another Class with following code:</p> <pre><code>package de.example.testprojekt; import android.content.Context; import android.util.AttributeSet; import android.util.Log; import android.view.LayoutInflater; import android.view.View; import android.widget.Button; import android.widget.LinearLayout; public class TestClass extends LinearLayout { LayoutInflater inflator; public TestClass (Context context) { super (context); initialize(); } public TestClass (Context context, AttributeSet attrs) { super (context, attrs); initialize(); } public TestClass (Context context, AttributeSet attrs, int defStyle) { super (context, attrs, defStyle); initialize(); } void initialize() { inflator = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); inflator.inflate(R.layout.secondary_activity, this); } @Override protected void onFinishInflate() { super.onFinishInflate(); setupLayout(); } Button button1; String TAG = "tag"; private void setupLayout () { button1 = (Button) findViewById(R.id.button1); button1.setOnClickListener(new OnClickListener() { public void onClick(View arg0) { Log.e(TAG,"test"); } }); } } </code></pre> <p>And here are my two XML Files:</p> <pre><code><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" > <LinearLayout android:id="@+id/linearLayout" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal" > <de.example.testprojekt.TestClass android:id="@+id/mainCtrl1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginRight="30dp" /> <de.example.testprojekt.TestClass android:id="@+id/mainCtrl2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginRight="30dp" /> </LinearLayout> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:layout_centerVertical="true" android:padding="@dimen/padding_medium" android:text="@string/hello_world" tools:context=".MainActivity" /> </code></pre> <p></p> <p>And the second one:</p> <pre><code><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" > <Button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:text="Button" /> </code></pre> <p></p>
