最佳答案

这是密码试试看
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>

这是活动代码
Button btn;
int CAMERA_PIC_REQUEST = 0;
ImageView imgView;

imgView = (ImageView) findViewById(R.id.img_preview);

    btn = (Button) findViewById(R.id.btn);
    btn.setCompoundDrawables(null, getResources().getDrawable(R.drawable.icon), null, null);
    btn.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent camera_intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(camera_intent, CAMERA_PIC_REQUEST);
                    }
      });

这是活动结果
@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);
            }
    }
}
