基本上,我想开始一个活动,打印出输入字符串和下面的图像.
在activity_display_message.xml中:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
android:orientation="vertical" >
<TextView
android:text="@+id/textView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
<ImageView
android:id="@+id/imageView2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="@drawable/serious" />
</LinearLayout>

这是OnCreate()中的代码:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_display_message);
Intent intent = getIntent();
String message = intent.getStringExtra(MainActivity.EXTRA_MESSAGE);
ImageView image2 = (ImageView) findViewById(R.id.imageView2);
// Create the text view
TextView textView = (TextView)findViewById(R.id.textView);
//textView.setTextSize(20);
textView.setText(message);
// Set the text view as the activity layout
// Show the Up button in the action bar.
setupActionBar();
}
