Question

This是我在模拟器中运行应用程序时遇到的错误消息。

错误日志中没有任何内容，它并没有真正告诉我错误的来源，但我在LogCat中得到了这个：

WARN/ActivityManager(51): Launch timeout has expired, giving up wake lock!

WARN/ActivityManager(51): Activity idle timeout for HistoryRecord{44e0fb68 com.gamer.network2/.FirstActivity}

WARN/InputManagerService(51): Window already focused, ignoring focus gain of: com.android.internal.view.IInputMethodClient$Stub$Proxy@44e98158

ERROR/gralloc(51): [unregister] handle 0x494d08 still locked (state=40000001)

这是我的应用程序启动时出现的Java版本:(我想如果这是首先出现的问题，那就是问题所在，但我真的不知道。）

package com.gamer.network2;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;

public class FirstActivity extends Activity {
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    TextView next1 = (TextView) findViewById(R.id.signuptext);
    next1.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            Intent myIntent = new Intent(view.getContext(), Screen2.class);
            startActivityForResult(myIntent, 0);
            finish();
        }

    });
}
}

这是我的清单：

我可以发布您需要的任何其他代码来帮助我。 =]

由于

Answer 1

我认为onClickListener仅用于按钮，而不是textviews

运行我的应用程序时，我一直收到错误消息？
