自己写的一个简单的Android终端模拟器

布局很简单，就不多说了，直接贴Activity的代码，主要用到的就是Runtime的exec()方法，需要注意的添加相应的users-permission，我刚开始测试ping命令的时候死活没有反应，后来才发现是忘了添加访问网络的权限造成的

package com.example.myandroidterminaltest;
    
    import android.os.Bundle;
    import android.support.v7.app.AppCompatActivity;
    import android.util.Log;
    import android.view.View;
    import android.widget.Button;
    import android.widget.EditText;
    import android.widget.TextView;
    import java.io.BufferedReader;
    import java.io.IOException;
    import java.io.InputStream;
    import java.io.InputStreamReader;
    
    public class MainActivity extends AppCompatActivity implements View.OnClickListener {
    
        private TextView content;
        private EditText input;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    
            content = (TextView) findViewById(R.id.content);
            input = (EditText) findViewById(R.id.input);
            Button button = (Button) findViewById(R.id.button);
            button.setOnClickListener(this);
        }
    
        @Override
        public void onClick(View v) {
            content.setText(getShellResult());
        }
    
        public String getShellResult() {
            String result = "";
            Runtime mRuntime = Runtime.getRuntime();
            try {
                Process mProcess = mRuntime.exec(input.getText().toString().trim());
                InputStream is = mProcess.getInputStream();
                InputStreamReader isr = new InputStreamReader(is);
                BufferedReader mReader = new BufferedReader(isr);
                String string;
                while ((string = mReader.readLine()) != null) {
                    result = result + string + "\n";
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
            return result;
        }
    }
