Question

无论用户点击纽顿,是否能够做到完全透明?

Below is some basic java that shows a button and when pressed starts a new intent. I also added the main.xml layout but I am not sure how to update it so the buttons fills the screen but is transparent.

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>

如果通过屏幕听听听用户互动是你的目标,我就建议给你的线索增加听众。这消除了布顿的必要性。

E.g.

LinearLayout layout = (LinearLayout) findViewById(R.id.your_layout);

layout.setOnTouchListener(new OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            return false;
        }
    });
});

XML:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/your_layout"
    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>

您可能必须包括以下进口:

import android.view.View.OnTouchListener;
import android.view.MotionEvent;
