我的意图是使用 openCV 在 Android 设备上运行模板匹配。我已经建立了新的 Android 项目来使用 openCV。我还在我的 Start.java 文件中添加了代码片段来初始化 openCV 库。在此之后，我无法在我的活动中显示任何控件。代码非常简单（空白），执行没有错误，但我什至无法在我的手机上看到自动的“Hello World”字符串，而且我无法以任何方式编辑活动。任何想法为什么？

Start.java 代码为：

package com.example.match;

import org.opencv.android.OpenCVLoader;

import android.os.Bundle;
import android.app.Activity;
import android.app.AlertDialog;

import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;

import org.opencv.core.Core;
import org.opencv.core.Core.MinMaxLocResult;
import org.opencv.core.CvType;
import org.opencv.core.Mat;
import org.opencv.core.Point;
import org.opencv.core.Scalar;
import org.opencv.highgui.Highgui;
import org.opencv.imgproc.Imgproc;

public class Start extends Activity {



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_start);
        if (!OpenCVLoader.initDebug()) {
            // Handle initialization error


    }}


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.start, menu);
        return true;
    }


}

这是 LogCat：
