- I am trying to use AutoResizeTextView on a simple activity, but it fails on the first go. If the button is touched to auto resize there is no problem. But, the thing is, i need it to be resized when the activity is first created.
- Here is the list of things i have tried: Created AutoRiseTextView in xml as a CustomView. Called "show_the_text" method twice on the start. Called the method twice with different texts. Moved container decleration to inside of onCreate. Used RelativeLayout insted of FrameLayout. Created a temporary TextView inside of FrameLayout with text in it.
- I run the application on API23 emulator and API21 phone but result is the same.
- I have to say that i am a begginer in programming. Any ideas are welcome.
- And this is the source code of AutoResizeTextView i used: https://github.com/AndroidDeveloperLB/AutoFitTextView
package com.kr.hakan.myapplication;
import android.graphics.Color;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.text.TextUtils;
import android.util.TypedValue;
import android.view.Gravity;
import android.view.View;
import android.view.ViewGroup;
import android.widget.FrameLayout;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//auto resizing fails on the first run
show_auto_resized_text();
//but when we use user touch it works
TextView button=(TextView) findViewById(R.id.text_button);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
show_auto_resized_text();
}
});
}
public void show_auto_resized_text(){
FrameLayout text_container=(FrameLayout) findViewById(R.id.container);
text_container.removeAllViews();
int width= text_container.getWidth()-40;
int height= text_container.getHeight()-40;
AutoResizeTextView textView=new AutoResizeTextView(MainActivity.this);
textView.setGravity(Gravity.CENTER_VERTICAL | Gravity.CENTER_HORIZONTAL);
textView.setMaxLines(10);
textView.setTextColor(Color.WHITE);
textView.setTextSize(TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_SP, height, getResources().getDisplayMetrics()));
textView.setEllipsize(TextUtils.TruncateAt.END);
textView.setLayoutParams(new ViewGroup.LayoutParams(width, height));
final String DOUBLE_BYTE_SPACE = "\u3000";
String fixString = "";
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.HONEYCOMB_MR1
&& android.os.Build.VERSION.SDK_INT <= android.os.Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1) {
fixString = DOUBLE_BYTE_SPACE;
}
textView.setText(fixString + "THIS IS MY TEXT TO BE AUTO RESIZED" + fixString);
text_container.addView(textView);
}
}
and the xml file
<?xml version="1.0" encoding="utf-8"?>
