如何在Android中以编程方式检查窗口小部件的类型？

Question

I want to check the type of a widget programmatically.

View v = tabHost.getTabWidget().getChildAt(i);

How do I check if v is a RelativeLayout or LinearLayout ?

Answer 1

View v = tabHost.getTabWidget().getChildAt(i);

if(v instanceof RelativeLayout) {
    // RelativeLayout
} else if (v instanceof LinearLayout){
    // LinearLayout
}

Although you probably should use findViewById() to find the Widget you want.

View v = tabHost.getTabWidget().findViewById(R.id.myLinearLayoutView);
