Question

我有一个Android应用程序，里面有一些活动，包括谷歌地图片段，我在主屏幕上有一个按钮来打开这个地图活动，当我点击按钮它只是一直崩溃应用程序。

贝娄是主要班级。

package com.test.finalproject;

import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.support.v4.app.FragmentActivity;

  public class MainActivity extends  ActionBarActivity implements View.OnClickListener {

Button buttonLogin;
Button buttonRegister;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);
    buttonLogin = (Button)findViewById(R.id.buttonLogin);
    buttonLogin.setOnClickListener(this);
    buttonLogin = (Button)findViewById(R.id.buttonRegister);
    buttonLogin.setOnClickListener(this);
}

private void buttonLoginClick()
{
    startActivity (new Intent("GoogleMaps"));
}

private void buttonRegisterClick()
{
    startActivity (new Intent("TextToo"));
}

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

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}



@Override
public void onClick(View v) {
    switch (v.getId())
    {
        case R.id.buttonLogin:
            buttonLoginClick();
            break;

    }
    switch (v.getId())
    {
    case R.id.buttonRegister:
        buttonRegisterClick();
        break;
        }
    }
  }

这是布局XML。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

<TextView
    android:background="@null"
    android:editable="false"
    android:cursorVisible="false"

    />

<fragment
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

</RelativeLayout>

这是清单。

@Override

    return false;
   }
}

这是一个日志的图像，它有更多的内容，我只是不知道如何导出它，我已经搜索了几天，并尝试了许多不起作用的不同解决方案。如果可以，请帮助我，谢谢你。

编辑：我没有足够的声望发布图片:(

Answer 1

问题很可能是xml中的textview。你既没有layout_width也没有layout_height属性。

<TextView
android:background="@null"
android:editable="false"
android:cursorVisible="false"

/>

将其更改为：

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@null"
android:editable="false"
android:cursorVisible="false"

/>

如上面评论中所述，在清单中的应用标记内添加Google Play服务的元数据标记：

<meta-data
    android:name="com.google.android.gms.version"
    android:value="@integer/google_play_services_version" />

Answer 2

你得到例外：

尝试实例化一个不是片段的com.google.android.gms.maps.SupportMapFragment类，如下所示：java.lang.ClassCastException

您正在使用MapActivity：GoogleMaps extends MapActivity表示您需要处理MapFragment而不是SupportMapFragment

您可以通过两种方式处理此问题：

<强> 1 将SupportMapFragment替换为MapFragment

<fragment
    android:name="com.google.android.gms.maps.MapFragment"
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

在这种情况下，您需要导入：

import android.app.Fragment;
import android.app.FragmentTransaction;

2。将MapActivity替换为FragmentActivity

在这种情况下，您需要导入：

import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentTransaction;

Answer 3

您的TextView没有正确的属性，您必须指定layout_width和layout_height！
