Question

我正在尝试在我的应用程序中扩展FloatingActionButton。当我尝试构建时，我收到编译器错误。如果我删除扩展FloatingActionButton的类，那么我的应用程序将编译

:app:transformClassesWithDexForDebug
UNEXPECTED TOP-LEVEL EXCEPTION:
Error:Execution failed for task ':app:transformClassesWithDexForDebug'.
> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home/bin/java'' finished with non-zero exit value 2

错误似乎只发生在我向extend类添加方法时。

此编译

public class TriedFAB extends FloatingActionButton {
    public TriedFAB(Context context) {
        super(context);
    }

    public TriedFAB(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public TriedFAB(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }
//    private void failCompile(){
//
//    }
}

这会导致编译器错误

public class TriedFAB extends FloatingActionButton {
    public TriedFAB(Context context) {
        super(context);
    }

    public TriedFAB(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public TriedFAB(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }
    private void failCompile(){

    }
}

看起来我的应用程序太大了，达到了dex限制

Answer 1

尝试这样。在xml中声明

<android.support.design.widget.FloatingActionButton
    android:id="@+id/myfloatingbutton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@android:drawable/ic_dialog_email"

    />

然后使用

 floatingActionButton=(FloatingActionButton)findViewById(R.id.myfloatingbutton);
    //handle FloatingActionButton Click
    floatingActionButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(getApplicationContext(),"FloatingActionButton is Clicked",Toast.LENGTH_SHORT).show();
        }
    });

点击dex限制，请参阅消息，而不是gradle控制台
