Here's a blogpost that does exactly what you need it to do. It has a complete code example on how to display the contents of the Logcat log. Here's the code:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
class ReadLogDemo extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
try {
Process process = Runtime.getRuntime().exec("logcat -d");
BufferedReader bufferedReader = new BufferedReader(
new InputStreamReader(process.getInputStream()));
StringBuilder log=new StringBuilder();
String line = "";
while ((line = bufferedReader.readLine()) != null) {
log.append(line);
}
TextView tv = (TextView)findViewById(R.id.textView1);
tv.setText(log.toString());
} catch (IOException e) {
}
}
}

1You might need permission to run Runtime.getRuntime().exec("logcat -d"); I think. exec causes problem from time to time due to permission issues. – Edison Oct 23 '11 at 02:12
