如何在imageview中显示android中照相机拍摄的照片

有人能告诉我们如何在安卓系统中使用前置摄像头拍摄的imageview照片中显示图片吗有人能提供代码吗

谢谢

这是代码，请尝试

这是我的xml文件

<?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:id="@+id/linear">
    <Button android:id="@+id/btn" android:layout_width="200dp"
        android:layout_height="wrap_content" android:text="Click" />
    <ImageView android:id="@+id/img_preview"
        android:layout_width="fill_parent" android:layout_height="fill_parent" />
</LinearLayout>

这是onActivityResult

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    switch(requestCode){
    case CAMERA_PIC_REQUEST:
        if(resultCode==RESULT_OK){
           Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
           imgView.setImageBitmap(thumbnail);
            }
    }
}

或者学习android的API演示，试试这个

public class TakingImage extends AppCompatActivity {

private static final int CAMERA_REQUEST = 1888;
private ImageView imageView;

public void onCreate(Bundle savedInstance){
    super.onCreate(savedInstance);
    setContentView(R.layout.activity_choosing_photo);
    button = (Button)findViewById(R.id.button_select);
    imageView = (ImageView)findViewById(R.id.image_view);
    Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
        Bitmap photo = (Bitmap) data.getExtras().get("data");
        imageView.setImageBitmap(photo);
    }
}

活动\u选择\u photo.xml

<ImageView
    android:id="@+id/image_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/flower"
    android:layout_marginLeft="100dp"/>
<Button
    android:id="@+id/button_select"
    android:layout_below="@+id/image_view"
    android:layout_marginTop="40dp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Select"
    android:layout_marginLeft="140dp"/>

这里回答了相同的问题：我想使用前置摄像头拍照检查您是否可以将“案例0:”更改为“案例摄像头图片请求”：

<ImageView
    android:id="@+id/image_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/flower"
    android:layout_marginLeft="100dp"/>
<Button
    android:id="@+id/button_select"
    android:layout_below="@+id/image_view"
    android:layout_marginTop="40dp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Select"
    android:layout_marginLeft="140dp"/>
