类似京东筛选 点击小按钮打对勾，没有点击取消

代码如下：

package widgets;

import android.util.AttributeSet;

import android.view.View;

public class SelectFPView extends View{

public SelectFPView(Context context, AttributeSet attrs) {

    }

    mBitmap=mBitmapDrawable.getBitmap();

    }  

    

    

    private boolean IsDrawBitmap;

}

 
}

private String text="";
private int fontWidth;
private int fontHeight;
@Override

}

public void setText(String txt){
this.text=txt;
}

}

使用

selectFPView.setText(flowModel.getStr());
selectFPView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
for (int j = 0; j < views.size(); j++) {
((SelectFPView) views.get(j)).setIsDrawBitmap(false);
}
if(selectFPView.isIsDrawBitmap()){
selectFPView.setIsDrawBitmap(false);

}else{
if(itemtxtOnclick!=null){
itemtxtOnclick.txtOnClick(pos);
}
selectFPView.setIsDrawBitmap(true);
}
selectFPView.invalidate();
}
});
