【问题描述】:
是否可以制作一个透明的全屏按钮,这样无论用户在哪里点击按钮都会被激活?
下面是一些基本的java,它显示了一个按钮,按下时会启动一个新的意图。我还添加了 main.xml 布局,但我不确定如何更新它,以便按钮填满屏幕但透明。
package com.MeetingManager;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Window;
import android.view.WindowManager;
import android.widget.Button;
public class MeetingManager extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
layout.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent e) {
Intent myIntent = new Intent(MeetingManager.this,CreateMeeting.class);
startActivityForResult(myIntent, 0);
}
});
}
}
XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/meetingbg"
>
<TableRow android:layout_height="wrap_content" android:layout_width="match_parent" android:id="@+id/tableRow5">
<Button android:text="Button" android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
</TableRow>
</LinearLayout>
