好的,所以在我问这个问题之前,我看过:
Android 底部导航栏重叠 Spinner。设置 Spinner 下拉高度/边距
但是,我还没有看到我认为可以解决我的特殊情况的方法。所以这是我的问题:我正在编写一个将在屏幕上显示图像的自定义 SurfaceView。在那个 SurfaceView 中,我在右下角绘制图像。这是代码:
import android.annotation.SuppressLint;
import android.app.Activity;
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.graphics.Point;
import android.os.Build;
import android.os.Bundle;
import android.view.Display;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
import android.view.WindowManager;
public class demosf extends Activity {
OurView v;
int Measuredwidth;
int Measuredheight;
WindowManager w;
Bitmap whatever;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Measuredwidth = 0;
Measuredheight = 0;
getScreenWidthAndHeight();
whatever = BitmapFactory.decodeResource(getResources(), R.raw.dragarrow);
v = new OurView(this);
setContentView(v);
}
public class OurView extends SurfaceView implements Runnable {
Thread t = null;
SurfaceHolder holder;
boolean isItOK;
public OurView(Context context) {
super(context);
holder = getHolder();
}
@Override
public void run() {
while (isItOK) {
try {
Thread.sleep((long) 50);
} catch (InterruptedException e) {
e.printStackTrace();
}
if (!holder.getSurface().isValid()) {
continue;
}
Canvas c = holder.lockCanvas();
c.drawARGB(255, 0, 0, 0);
c.drawBitmap(whatever, ((float) Measuredwidth - (float) whatever.getWidth()), ((float) Measuredheight - (float) whatever.getHeight()), null);
holder.unlockCanvasAndPost(c);
}
}
public void pause() {
isItOK = false;
while (true) {
try {
t.join();
} catch (InterruptedException e) {
e.printStackTrace();
}
break;
}
t = null;
}
public void resume() {
isItOK = true;
t = new Thread(this);
t.start();
}
}
@Override
protected void onPause() {
super.onPause();
v.pause();
}
@Override
protected void onResume() {
super.onResume();
v.resume();
}
@SuppressLint("NewApi")
@SuppressWarnings("deprecation")
public void getScreenWidthAndHeight() {
Point size = new Point();
w = getWindowManager();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2) {
w.getDefaultDisplay().getSize(size);
Measuredwidth = size.x;
Measuredheight = size.y;
} else {
Display d = w.getDefaultDisplay();
Measuredwidth = d.getWidth();
Measuredheight = d.getHeight();
}
}
}
为了彻底,这也是清单:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.something"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.example.something.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.example.something.demosf"
android:label="@string/app_name"
android:screenOrientation="landscape"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
>
<intent-filter>
<action android:name="com.example.something.DEMO" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
</manifest>
现在我似乎遇到的问题是,在我的 Nexus 7 上,这完全符合我的预期。然而,在我的朋友 Toshiba Thrive 上,图像的底部被底部的条截断了。这是比较: Nexus7 在右边,Thrive 在左边。所以我的问题是:到底发生了什么,我该如何解决这个问题?(最好适用于所有 Android 版本)哦,附带问题:那个底栏到底叫什么?哈哈
编辑:我知道这不是最好的代码,我只是使用此代码来演示正在发生的事情,并且可能会为我的“getScreenWidthAndHeight()”方法找到一种不同的方法,它可以解释它发生在设备中的这种奇怪的重叠
