java代码

   public void login(View v) {
    email = edtLogin.getText().toString();
    pwd = edtPassword.getText().toString();

    postParam = new HashMap<String, String>();
    postParam.put("username", email);
    postParam.put("password", pwd);
    postParam.put("grant_type", "password");

    JSONObject object = new JSONObject(postParam);
    Type type = new TypeToken<LoginResponse>() {
   }.getType();
    // GeneralRequest.login(LoginActivity.this, type, object, LoginActivity.this, LoginActivity.this);
    callApi(postParam);
}

XML where the method is called:
 <Button
    android:id="@+id/login"
    android:layout_width="@dimen/width_400"
    android:layout_height="wrap_content"
    android:background="@drawable/btn_background"
    android:layout_below="@+id/password"
    android:layout_centerHorizontal="true"
    android:onClick="login"
    android:text="Login"
    android:textStyle="bold"
    android:textAllCaps="false"
    android:layout_marginTop="@dimen/margin_corner"
    android:textColor="@android:color/white"
    />

GRADLE APP文件 - 

apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "24.0.0 rc2"

defaultConfig {
    applicationId "com.mycompany.soilreport"
    minSdkVersion 15
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
    multiDexEnabled true
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'),      'proguard-rules.pro'
    }
}

dexOptions {
    incremental = true;
    preDexLibraries = false
    javaMaxHeapSize "4g" // 2g should be also OK
}
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:multidex:1.0.1'
compile 'com.android.support:appcompat-v7:23.3.0'
compile 'com.android.support:design:23.3.0'
compile 'com.mcxiaoke.volley:library:1.0.19'
compile 'com.google.code.gson:gson:2.4'

compile 'com.code-troopers.betterpickers:library:2.5.3'
compile files('libs/itextg-5.5.4.jar')
}

到目前为止我尝试过的事情：

  1. 重启android studio
  2. 重新启动geny motion
  3. 重新启动我的笔记本电脑。
  4. 再次克隆项目
  5. 检查了java版本和gradle版本
  6. 卸载了apk并重新安装
  7. 检查所有变量的初始化

    8. 任何人都可以解释为什么我的构建文件有问题吗？

1 个答案:

答案 0 :(得分：0)

public class MainActivity extends Activity { 

public void login(View v) {
email = edtLogin.getText().toString();
pwd = edtPassword.getText().toString();

postParam = new HashMap<String, String>();
postParam.put("username", email);
postParam.put("password", pwd);
postParam.put("grant_type", "password");

JSONObject object = new JSONObject(postParam);
Type type = new TypeToken<LoginResponse>() {
}.getType();
// GeneralRequest.login(LoginActivity.this, type, object,  LoginActivity.this, LoginActivity.this);
callApi(postParam);
}

//activity oncreated method and other override methods

}

这里注意到我告诉你的一件事，你应该将你的onclick方法放在你的活动中但是在＆＃34; @ override＆＃34;之外。方法因为那些是活动生成的方法。
