我試圖在我的Android應用程序上顯示一張圖像（一條蛇），該圖像可能會在上出現電路板表（這是一個tablelayout）。我怎麼能這樣做，而不是簡單地顯示圖像以上的表？如何在Android中的桌面上顯示圖像
package com.example.test;
import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TableLayout;
import android.widget.TableRow;
import android.widget.Toast;
public class MainActivity extends Activity {
TableLayout table;
ImageView image;
private static final int TABLE_WIDTH = 12;
private static final int TABLE_HEIGHT = 10;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
table = (TableLayout) findViewById(R.id.view_root);
image = (ImageView) findViewById(R.id.imageView1);
// Populate the table with stuff
for (int y = 0; y < TABLE_HEIGHT; y++) {
final int row = y;
TableRow r = new TableRow(this);
table.addView(r);
for (int x = 0; x < TABLE_WIDTH; x++) {
final int col = x;
Button b = new Button(this);
b.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Toast t = Toast.makeText(getApplicationContext(), "You clicked (" + row + "," + col + ")", Toast.LENGTH_SHORT);
Toast t = Toast.makeText(getApplicationContext(), "Tooth cavity in 6 month\n (previously in 2 years)", Toast.LENGTH_SHORT);
t.getView().setBackgroundColor(Color.RED);
t.show();
if(row==0 && col==0){
image.setImageResource(R.drawable.snake);
}
else{
image.setVisibility(View.GONE);
}
}
});
r.addView(b);
}
}
}
}
而且佈局：
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/view_root"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:shrinkColumns="*"
tools:context=".MainActivity" >
<ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</TableLayout>
