android实现点击TextView显示隐藏控件

实用代码分享，实现点击几次某个控件，显示隐藏功能。代码很简单但却很实用，比如可以实现测试环境和正式环境的切换功能，隐藏提交应用日志等等。

直接上代码

Activity

[code=language-java]public class MainActivity extends AppCompatActivity {
//全局属性
private TextView mTitleView;
private Spinner mSpinnerView;
private int touchCount = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initView();
setListener();
}

private void initView(){
mSpinnerView = (Spinner) findViewById(R.id.spinner);
mSpinnerView.setVisibility(View.INVISIBLE);
mTitleView = (TextView) findViewById(R.id.textViewTitle);
}

private void setListener(){
mTitleView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
touchCount += 1;
if (touchCount == 5) {
mSpinnerView.setVisibility(View.VISIBLE);
touchCount = 0;

} else {
Toast.makeText(getApplicationContext(), "Click more  " + Integer.toString(5 - touchCount), Toast.LENGTH_SHORT).show();
}
}
});
}
}

代码中设置spinner值，并设置监听事件

[code=plain]       //赋值
String[] arrayStr= { "111", "222", "333", "444", "555" }; //定义数组
//将可选内容与ArrayAdapter连接，
ArrayAdapter adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, arrayStr);
mSpinnerView.setAdapter(adapter);
//设置监听事件
mSpinnerView.setOnItemSelectedListener(new Spinner.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
String selectEmail = getResources().getStringArray(R.array.select_email)[position];
String usename = userNameArray[position];
mEtEmail.setText(selectEmail);
mEtName.setText(usename);
}

@Override
public void onNothingSelected(AdapterView<?> parent) {

}
});
