当我执行我的Android应用程序时,它工作正常,除了视图不会填满屏幕。我正在使用以下xml文件:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
>
<com.project.name.SplashView
android:id="@+id/splashView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</LinearLayout>
我定义了一个自定义视图,扩展了常规视图,我覆盖了onDraw方法以显示启动画面。在代码中,我通过简单的调用设置布局:
setContentView(R.layout.splash);
我不会发布我的onDraw方法,因为它有一堆动画代码。但是,我通过使用这个函数简单地将画布的背景变白来测试视图边界(所以我知道它没有填满屏幕):
private void drawBackground(Canvas c)
{
Paint p = new Paint();
p.setColor(Color.WHITE);
c.drawRect(0, 0, c.getWidth(), c.getHeight(), p);
}
任何有想法的人?

奇怪的是,我接受了你的代码,并且能够毫无问题地使其工作。我针对2.2编译了我的测试,并在2.3.3模拟器上运行它。代码在下面提供,并在此处输入:
屏幕的哪个区域未正确绘制?如果它是标题栏和通知区域,请参阅下面清单中的我的评论:
的AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.koderutils.example.customviewfull"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="9" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<!--
NOTE: If you want the Activity to take up the entire screen, add this attribute.
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
-->
<activity
android:label="@string/app_name"
android:name=".ExampleCustomViewFullActivity">
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
ExampleCustomViewFull.java:
package com.koderutils.example.customviewfull;
import android.app.Activity;
import android.os.Bundle;
public class ExampleCustomViewFullActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
CustomView.java:
package com.koderutils.example.customviewfull;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.util.AttributeSet;
import android.view.View;
public class CustomView extends View {
public CustomView(Context context) {
super(context);
}
public CustomView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CustomView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
protected void onDraw(Canvas c) {
super.onDraw(c);
Paint p = new Paint();
p.setColor(Color.WHITE);
c.drawRect(0, 0, c.getWidth(), c.getHeight(), p);
}
}
main.xml中:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<com.koderutils.example.customviewfull.CustomView
android:id="@+id/custom_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</LinearLayout>

我设法通过确保将minSDKVersion设置为至少8来解决问题。
