ActionBar 中实现分享（又有个坑）

忘是亡心i 2022-09-26 02:22 96阅读 0赞

import android.support.v7.widget.ShareActionProvider;

MenuItem item =menu.findItem(R.id.action_settings);
     shareActionProvider=(ShareActionProvider) MenuItemCompat.getActionProvider(item); /* shareActionProvider=(ShareActionProvider) item.getActionProvider();*///要是用这句报错

item中的ShareActionProvider和在MainActitity中导入的ShareActionProvider是同一个包中的

下面是实现的代码

public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.menu_main, menu);
        MenuItem item =menu.findItem(R.id.action_settings);
         shareActionProvider=(ShareActionProvider) MenuItemCompat.getActionProvider(item);
    
      /* shareActionProvider=(ShareActionProvider) item.getActionProvider();*/ return true;
    }

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();
    
        //noinspection SimplifiableIfStatement if (id == R.id.action_settings) {
    
    
            Intent intent = new Intent(Intent.ACTION_SEND);
            intent.setType("text/plain");
            intent.putExtra(Intent.EXTRA_TEXT, "aa");
            shareActionProvider.setShareIntent(intent);
            return true;
    
        }
    
        return super.onOptionsItemSelected(item);
    }
