Java 在ImageView中导入图像

我在java片段中有这段代码，正如您所看到的，我在每个项目中都导入了textview。我没有尝试为我的每个项目导入imageview，例如：

问题已经解决了。见下文

    img1 = (ImageView) rootView.findViewById(R.id.img1);
    img1.setBackgroundResource(R.drawable.pickmeup);

以下是新代码：

package info.androidhive.tabsswipe;

import com.sothree.slidinguppanel.SlidingUpPanelLayout;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.util.Log;
import android.view.KeyEvent;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnKeyListener;
import android.view.ViewGroup;
import android.widget.TextView;
import android.widget.ImageView;
import dk.appografen.joeandthejuice.R;

public class MenuDetailsFragment extends Fragment {

    TextView textView;
    View rootView;
    ImageView img1;
    private SlidingUpPanelLayout mLayout;

    //Juice

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle          savedInstanceState)             {

        if (name.equals("PICK ME UP")) {
            rootView = inflater.inflate(R.layout.menu_details_slide, null, false);
            mLayout = (SlidingUpPanelLayout) rootView.findViewById(R.id.sliding_layout);
            textView = (TextView) rootView.findViewById(R.id.textView1);
            textView.setText("" + name + "");

也许你应该试试这样：

imageView.setImageResource(R.drawable.randomimage);

试试这个

mImageView.setImageDrawable(getResources().getDrawable(R.drawable.randomimage));

请解释OP有什么问题，以及为什么这可以通过编辑您的答案来解决问题。setImageResource（/**Resource Id**/）在UI线程上执行位图解码，并可能导致延迟中断。因此，setImageDrawable（）成为更好的选项，因为您的片段尚未附加到您的活动。是否有此帮助？从中获得：无法对非静态方法setImageDrawable（Drawable）进行静态引用从类型ImageView@Wanaclem“通过编辑您的答案！”请阅读经验丰富的用户的评论，这些用户试图更仔细地帮助您。完整的答案应该是答案本身，而不是评论中的某个地方。这很接近。但正确的答案是：img1=（ImageView）rootView.findviewbyd（R.id.img1）；img1.收穗地资源（R.可提取.拾穗）；
