推荐答案

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;
import java.io.IOException;
import java.io.InputStream;

public class MainActivity extends AppCompatActivity {

    TextView textView ;
    ProcessBuilder processBuilder;
    String Holder = "";
    String[] DATA = {"/system/bin/cat", "/proc/cpuinfo"};
    InputStream inputStream;
    Process process ;
    byte[] byteArry ;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        textView = (TextView)findViewById(R.id.textView);

        byteArry = new byte[1024];

        try{
            processBuilder = new ProcessBuilder(DATA);

            process = processBuilder.start();

            inputStream = process.getInputStream();

            while(inputStream.read(byteArry) != -1){

                Holder = Holder + new String(byteArry);
            }

            inputStream.close();

        } catch(IOException ex){

            ex.printStackTrace();
        }

        textView.setText(Holder);
    }
}
