Android相机 - 一半的屏幕是黑色人像模式 [英] Android Camera - Half of the screen is black in Portrait mode
问题描述
我试图创造的相机应用,但我已经遇到这个问题:在横向模式下使用相机时一切正常,但使用与setDisplayOrientation纵向(90)方法带来了这个问题:
一半的屏幕是黑的。

surfaceCreated方式:
@覆盖
公共无效surfaceCreated(SurfaceHolder持有人){
尝试{
this.camera = Camera.open();
this.camera.setDisplayOrientation(90);
this.camera.set previewDisplay(this.holder);
}赶上(IOException异常五){
e.printStackTrace();
}
}
我的XML布局
<?XML版本=1.0编码=UTF-8&GT?;
< LinearLayout中的xmlns:机器人=http://schemas.android.com/apk/res/android
机器人:layout_width =match_parent
机器人:layout_height =match_parent
机器人:方向=垂直>
<的FrameLayout
机器人:ID =@ + ID /摄像机preVIEW
机器人:layout_width =match_parent
机器人:layout_height =0dip
机器人:layout_weight =1>
< /&的FrameLayout GT;
<按钮
机器人:ID =@ + ID / analyzeButton
机器人:layout_width =match_parent
机器人:layout_height =WRAP_CONTENT
机器人:文字=@字符串/分析/>
< / LinearLayout中>
顺便说一句,与亚行采取截图 - 相机正常显示。
测试的的Xperia ST27i的三星Galaxy掌上 - 同样的结果。
感谢您

{
//表面有被创建,获取摄像机,并告诉它来绘制。
mCamera = Camera.open();参数PARAMS = mCamera.getParameters();如果(this.getResources()。getConfiguration()。方向!= Configuration.ORIENTATION_LANDSCAPE)
{
params.set(方向,肖像);
mCamera.setDisplayOrientation(90);
}尝试
{
mCamera.set previewDisplay(支架);

赶上(IOException异常除外)

尝试这些code的朋友...............
I was trying to create camera app, but I have faced this issue : when using camera in landscape mode everything is OK, but using in portrait with setDisplayOrientation(90) method brings up this issue:
Half of the screen is black.

surfaceCreated method:
@Override
public void surfaceCreated(SurfaceHolder holder) {
try {
this.camera = Camera.open();
this.camera.setDisplayOrientation(90);
this.camera.setPreviewDisplay(this.holder);
} catch (IOException e) {
e.printStackTrace();
}
}
My XML layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<FrameLayout
android:id="@+id/cameraPreview"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1" >
</FrameLayout>
<Button
android:id="@+id/analyzeButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/analyze" />
</LinearLayout>
By the way, in screenshots taken with ADB - camera is shown normally. Tested on Xperia ST27i an Samsung Galaxy Pocket - same results.
Thank you
public void surfaceCreated(SurfaceHolder holder)
{
// The Surface has been created, acquire the camera and tell it where to draw.
mCamera = Camera.open();
Parameters params = mCamera.getParameters();
if (this.getResources().getConfiguration().orientation != Configuration.ORIENTATION_LANDSCAPE)
{
params.set("orientation", "portrait");
mCamera.setDisplayOrientation(90);
}
try
{
mCamera.setPreviewDisplay(holder);
}
catch (IOException exception)
{
mCamera.release();
mCamera = null;
}
}
